Why Your Brain is Your Largest Sex Organ

Sex and Your Brain

Often when we talk about the risks of sex, we focus on the physical risks such as pregnancy and STDs (sexually transmitted diseases). Other times we talk about the emotional risks involved with sex, but we rarely discuss the psychological consequences, or how sex affects your brain. Advances in neuroscience have made it possible to study how the brain is active and even how it is altered by sexual activity.

Why Your Brain is Your Largest Sex Organ?

During sex there are three prominent neurochemicals that are involved and each has a significant affect on your brain.

Dopamine: This chemical is present in men and women. Dopamine is a “reward chemical” in that it rewards people by saturating their brain with a feeling of exhilaration when that persons engages in the activity (in this case sex). Unfortunately, dopamine doesn’t know the difference between positive and negative behaviors and so it rewards the brain for both types of actions, things such as acing a test or speeding. Dopamine is the chemical that is responsible for the addictive nature of sex. It keeps you wanting that next fix.

Oxytocin: This is found in the female and is the bonding chemical. When this is released, it increases her desire for touch and causes her to bond to the person she is in physical contact with. With intercourse and orgasm, oxytocin washes over the brain, causing her to want more sex with the person she is bonded with. Like dopamine, oxytocin doesn’t discriminate. The result can be that a woman becomes bonded with someone she only thought would be a casual hookup.

Vasopressin: This is the male version of the bonding chemical and is the cause of the man’s connection with the woman. Again, it is non-discriminatory and may result in an unintentional connection with a partner.

“Sex Brain” and Bad Decisions

Understanding how these chemicals work can explain why people make bad decisions and helps us better understand the consequences. Often people jump into sex too soon. One reason for this is sex rewires the brain to make it easier to say yes to more sex. The part of the brain that regulates sexual restraint is weakened. They crave the release of dopamine. This helps explain why after a breakup, once a new relationship has begun it can progress quickly to a sexual relationship.

Another affect is that sex can keep people in bad relationships. Most of us know couples that stay in unhealthy, even abusive relationships and find ourselves asking why. It’s the sex. The bonding chemicals create such a strong attachment, even if there is no other foundation for the relationship that they can’t leave each other.

A third affect is that when a person engages in patterns of dating, having sex, breaking up finding a new partner, or just casually hooking up, that person potentially makes it more difficult to later bond with a spouse. By disrupting the function of the bonding chemicals, this pattern can break the circuits needed for long-term commitment. It becomes addicted to the sex without the emotional connection.

These affects can last a long time, affecting the person’s ability to emotionally invest and be committed to future relationships.

Safe Sex is about more than wearing a condom. It’s about protecting yourself physically, emotionally and psychologically. It’s about understanding the risks in all three areas and taking the steps to keep yourself safe. After all, you’re worth it! If you are struggling with the physical, emotional or psychological affects of sexual activity and would like to talk to someone, our team is available.

How Does Abortion End My Pregnancy?

May 29, 2026

If you’ve recently learned you are pregnant unexpectedly, we understand how overwhelming this might feel right now. If you're considering abortion as an option, taking time to understand how the process works is important so you can make an informed decision. Collage is here to help provide you with confidential support and abortion information at no cost. We offer a safe space, free of judgment, where you can think calmly about your options, receive lab-quality pregnancy testing, and get a complimentary ultrasound so you can get the facts around your pregnancy and learn what options are available to you. Schedule your free appointment today. Medical Abortion Medical abortion, also known as the abortion pill, ends a pregnancy by using two drugs taken at different times. The first pill, mifepristone, works by blocking progesterone and causes the embryo’s death. The second drug, called misoprostol, is usually taken a day or two after and causes the uterus to contract, expelling the pregnancy tissue through cramping and bleeding. Common side effects can include bleeding and cramping, bleeding with blood clots, and a low-grade fever. Medical abortion is only approved through ten weeks of gestation by the FDA . Follow-up care is typically recommended after a medical abortion to make sure the process is complete. Surgical Abortion Surgical abortion terminates a pregnancy in a clinic or medical setting and involves removing pregnancy tissue from the uterus through a suction device or a tool called a curette. This can also be called dilation and evacuation or dilation and curettage . Common side effects of surgical abortions are bleeding and cramps. You may also have a late or early period as your uterus has to build a new lining after the procedure. What Are The Risks Of Abortion? Medical and surgical abortion both have possible risks that you should be aware of. Some women may also experience emotional responses afterward. Complications that can arise from abortion are: Infection. Scar tissue on the uterine wall, known as Asherman's syndrome . Heavy bleeding that may not stop. Diarrhea and digestive pain. An incomplete abortion. Confirm Your Pregnancy With An Ultrasound Before making a pregnancy decision, it is important to verify your pregnancy with an ultrasound. An ultrasound provides important medical details such as how far along you are, the location of the pregnancy, and whether a heartbeat is detected. These details are important since the abortion pill is not FDA-approved for over ten weeks, and it also rules out ectopic pregnancy, which requires urgent medical attention. As many as 26% of all pregnancies end in a miscarriage, and you can still get a positive pregnancy test result for days or weeks after a miscarriage because it takes time for hCG to leave the body. An ultrasound will confirm whether or not you have miscarried. We provide no-cost pregnancy services at our center, including limited OB ultrasounds, so you can get informed about your pregnancy and options.

What Are the Side Effects of the Abortion Pill?

April 21, 2026

Facing an unexpected pregnancy brings up a lot of questions, and it makes complete sense that you want to understand every option before deciding anything. If you're considering the abortion pill, knowing what it actually involves, including its side effects, is an important part of making a decision based on the facts. You don't have to sort through this alone. Schedule a no-cost appointment with Collage today to get your questions answered. How the Abortion Pill Works The abortion pill uses two drugs taken in sequence. The first, mifepristone, blocks progesterone, a hormone that supports the growth and development of the pregnancy. Without it, the pregnancy detaches from the uterine lining. The second drug, misoprostol, is typically taken at home and causes the uterus to contract and expel the pregnancy tissue. Heavy bleeding and cramping will be part of this process, and some women have described the pain as more severe than they anticipated. Side Effects to Know Beyond bleeding and cramping, the abortion pill can also cause these side effects : Upset stomach Vomiting Diarrhea Headache Fever Chills These side effects vary from woman to woman, which is one reason having a healthcare provider involved matters. Without medical oversight, it can be difficult to know what's within the range of normal and what requires immediate attention. Your personal health history also plays a role in how your body responds. Speaking with a medical professional before proceeding is an important step in protecting your well-being. Why an Ultrasound Matters First Before considering any pregnancy option, an ultrasound provides information that a pregnancy test simply cannot. It can confirm whether the pregnancy is progressing, rule out an ectopic pregnancy , and tell you how far along you are. The FDA approves the abortion pill only through 10 weeks gestation, making that last detail a critical piece of information for your safety. We're Here for You Whatever you're feeling right now, there’s no pressure here. At Collage, we genuinely care about you and want to make sure you have everything you need to make a sound decision.

3 Things to Know if You Are Considering Mail-Order Abortion

March 26, 2026

Facing an unexpected pregnancy can bring a lot of emotions, and often, a sense of urgency to make a decision quickly. You may have seen options online to order abortion pills by mail and wondered if it’s a simple solution. Before making a decision, it’s important to understand how this option could affect your health and what steps you can take to make a fully informed decision. 1. Your Health Should Always Come First Mail-order abortion often skips important medical safeguards. In many cases, there is no in-person evaluation before receiving the drugs. That means key health factors, such as your medical history and potential risks, will not be fully considered. There can also be uncertainty about the source of the drugs, including how they were handled, stored, or dosed. In fact, the FDA does not recommend this option because the drugs’ quality, safety, and effectiveness cannot be guaranteed. Taking time to understand your health first is a smart and proactive way to protect yourself. 2. You Need Clear Answers About Your Pregnancy A pregnancy test alone doesn’t give you the full picture. Before considering abortion, it’s important to confirm details about your pregnancy through an ultrasound. An ultrasound can tell you: How far along are you? Whether the pregnancy is developing (or if you’ve miscarried ) Where the pregnancy is located These details matter more than you might think. Abortion pills are FDA-approved only through 10 weeks of gestation, and without accurate dating, it’s possible to miscalculate how far along you are. An ultrasound can also detect an ectopic pregnancy , which occurs outside the uterus and requires immediate medical attention. Abortion pills will not treat this condition. What’s more, if you’ve experienced a miscarriage, you may require medical follow-up to prevent complications. Getting these details first helps ensure your safety. We offer limited OB ultrasounds following positive lab-quality pregnancy testing with us. 3. It’s Important to Understand the Process and Risks Mail-order abortion may sound straightforward, but it’s important to know what it may actually involve. The process includes significant cramping and bleeding as the body expels the pregnancy, with some women describing the pain as being unexpectedly severe . Other side effects can include: Nausea or vomiting Fever or chills Diarrhea Headaches There are also potential risks , such as heavy bleeding, infection, or an incomplete abortion that may require additional medical care. Without in-person support, it can be difficult to know what’s expected and when something may need medical attention. You Don’t Have to Figure This Out Alone When everything feels overwhelming, it can help to take a moment to evaluate your next steps and get the information you need. At Collage, we provide no-cost, confidential services so you can ask questions, gather accurate information, and explore your options at your own pace in a one-on-one setting.
