Why do people in a FWB relationship tend to fall in love? Sex is just sex. Think again.
I’m sure you’ve taken a biology course or have heard of hormones such as dopamine, oxytocin, and vasopressin. There are many hormones involved in sex, but these are the three main hormones I’ll be introducing today. They are also responsible for making you fall head over heels for that person you tried not to.
What do these hormones do?
Oxytocin (The Cuddle Hormone) is responsible for a deep bond with another human. According to the NCBI, oxytocin is released during sexual activity, penile erection, ejaculation, and social bonding (2011). In a casual sexual relationship, this hormone is constantly released no matter how you feel.
Dopamine is the pleasure hormone. News-Medical has mentioned that dopamine is responsible for rewarding pleasure, such as; food, sex, and possible drugs (2015). Therefore we may become addicted to the casual sex and want to see this person more.
Vassoprasine is known as the monogamy hormone. It tricks you into committing to only one person. Both sexes create this hormone, but men are influences the most. According to researchers, it promotes partner recognition, sexual arousal, courtship behavior, monogamy, pair bonding, and mate guarding. When you think your sex partner is becoming clingy or jealous, this is why. This hormone is released with oxytocin after sex.
Next time you have sex with someone casually, recognize that there is a high chance you could end up falling for them. Your body doesn’t care what your mind thinks.
