Is my nipple heal normally after some weeks? or I want to do some medicine?
Ouch! What a D I C K haha jk ahhh I would say wash it with hydrogen peroxide so it won't get infected then rub some neosporin on it. If it doesn't get better, or starts feeling worse over time, then it may be something to go to the doctor for, by for now, just keep the area really clean and maybe put your boyfriend on a leash next time ;)
