hey, I am a guy and my right nipple just recently got really sensetive when I bump it or press on it. why is that?
how old are you? cos a few years ago, when i was about 13 i had the same thing. A lump grew in each nipple and they were sore fore a while. It went down after a few months and the lump disappeared. Loads of other boys in my year also had this. I think its just something that happems as you go through puberty.
