Well, for one you shouldn't be having sex.
But usually after sex, men tend to have sperm in there penis still & you gotta pee it out. Don't ask me why its black... Maybe your sperms are emo.
Go learn something whats wrong with your parents letting you around girls?? kids your age should be doing homework watching tv and playing family games NOT THINKING ABOUT SEX!!! If my child wouldn't even be around a boy until she is 18years old and STILL won't be thinking about sex. Do you want kids your age?? you wouldn't even know what to do with a child. You can't even get a full time job unless a summer time amusement park which is not a lot of money to raise a child.
that's pretty jacked up. you're only 14! I'm 14 and i wouldn't actually have sex with someone even if i was drunk i would have enough sense to not do that. And go see a doctor but not a pediatrician cuz they would be like wat the hell? Also, anybody else who reads this, don't lecture me about drinking alcohol cuz it's not often or much.
sounds like an std, i'm not gonna lecture you about your choices and age but you need to talk to your parents or a trusted adult because discharge should no be black the only dark discharge should be blood so go get that checked up in the mean time no sex ok if its an sti or std you could be contagious
