sex

It depends if you are a girl or a boy. Nothing happens to boys physically but their self-confidence definitely grows. Girls have their hymens broken, may bleed for the day or the following few days and that's it.

Actually, girls could also get bacterial infection from their first time but not necessarily. If this happens, she could experience symptoms like frequent urge to bee, burning down there, dribbling, etc

Im still a virgin but for boys or girls its the same (can hurt for guys too my brother told me it hurt for him) but its not comman...and both girls and boys have risk of sexual diseases without protection
