hey guy's, didn't now exactly where to put this, but it's a concern of mine. i have an 8th grade cousin, and it seem's that his nipples are starting to poke out and are starting to hurt. he's very small, about 100 lbs. with now muscular development. do you think it's a puburty thing or does his body just need to develop. he's constantly made fun of about it. just wondering what's going on
