Oxytocin causes a woman to bond emotionally and misread the bond for something deeper, making it difficult to stay detached. This means that while the guy in your hookup may be able to move on, youre still feeling connected to him. They end up feeling hurt, depressed and lonely.

Is it normal to feel bad after a hookup?

“Feeling depressed after intercourse could simply result from the fact that you arent physically or emotionally ready for sex,” says sex therapist Robert Thomas. “Feeling guilt and emotionally distant post-sex might be an indication that you dont have a deep enough connection with your partner.”
