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.

An unexpected pregnancy can leave you with more questions than answers. Especially when friends are urging you to choose abortion, you may be more confused than ever. While their advice might come from care or fear, it’s essential to remember this is your pregnancy, future, and choice. At Collage, we’re here to help you navigate this pressure and find a path that feels right for you so that you can feel informed and confident about your decision. Reach out to us today for no-cost support. Listen to Your Instincts Your friends might be an important part of your life, but your instincts matter most. If abortion doesn’t feel right, take a moment to ask: What’s holding me back? Maybe you’re picturing parenting your child or are curious about adoption.  It’s also important to keep in mind that abortion is a serious procedure that your friends may not fully grasp the details of. Physical and emotional risks are involved, making it a more complex decision. Your hesitation is a sign to slow down and explore, not to rush into a choice you’re not ready for. Talk It Out If your friends keep pressing, try a gentle conversation. Let them know you understand they’re worried, you’re not sure about abortion yet. Ask what’s driving their advice. Maybe they’re scared about your finances or future. Maybe they’re simply telling you what they’d do in your situation, but that doesn’t mean it’s right for you. Understanding their side can ease tension without giving in. If they won’t respect your space, set boundaries and let them know you need time to think. You don’t owe them an immediate answer. Find Your Support Surround yourself with people who’ll lift you up, not pull you down. Write down your thoughts or talk to someone neutral. You can find a counselor or even online spaces where you can share your heart with those who won’t push one option over another. Even a trusted family member, a mentor, or a place like Collage can offer perspective without strings. You deserve to make this decision with clear facts and a steady heart, not under pressure.

An unexpected pregnancy can flip your world upside down, and the urge to keep it under wraps might hit hard. Maybe you’re thinking abortion could erase the situation quietly.

What do you do when those closest to you start pushing you toward a decision that doesn’t feel right? Pressure from family or friends to choose abortion can leave you feeling stuck, unheard, and unsure of what to do next. How can you hold firm in your decision while dealing with well-meaning but overwhelming advice? Here’s what you can do to navigate this difficult situation with strength and resilience. Mental Health and Pressure Your decision should be your own—one that isn’t influenced by guilt or outside expectations. Studies show that women who feel pressured into abortion are more likely to experience guilt, anxiety, depression, and other negative mental health outcomes. Protecting your mental and emotional health starts with making a choice that aligns with what you truly want. Ways to Handle the Pressure Since you understand why this decision needs to be yours, here are some practical steps to help you handle outside pressure. Give Yourself Time You don’t have to decide right away. Take a moment, think through your feelings, and give yourself the gift to reflect without feeling rushed. You're less likely to regret a decision made on your terms. Learn About All Your Options Abortion isn’t your only choice. Parenting and adoption are also possibilities, each with its own forms of support and resources. Learning more about these options can help you make an informed decision you feel at peace with. Set Boundaries It can be tough to stand your ground when others have strong opinions about your decision. Clearly expressing your thoughts by setting boundaries can help you avoid unwanted pressure. Letting others know you need time and space to think can help shift the conversation away from their influence and back to what’s best for you. Advice from a Third Party Getting a different perspective on your situation can be helpful when seeking advice from someone outside your inner circle. This could be a professional counselor, an online support group, or a caring team member at Collage . You deserve people in your life who want to understand you without judgment. You Are Not Alone Even if those around you don’t fully understand, there are people who do. A supportive environment can make all the difference as you navigate this decision. Collage is here to walk with you during this time. We offer lab-quality pregnancy testing, limited OB ultrasounds, pregnancy options information, and more at no cost so you can get informed and have the support you need to move forward with certainty.
