Why do guys have nipples?!
Question:
Why do guys have nipples?
Answers:
It has to do with embryonic development. The early embryo does not have specific male or female features and starts with a basic template that apparently includes nipples. If males are exposed to the appropriate hormones, they develop real breast tissue just like women do.
Other possible reasons are a) God's practical joke on us, or, more likely, b) they are there for guys who like to put piercings through them (had a guy today who had his girlfriend remove one tongue piercing and two nipple piercings before he went to the operating room. He cried like a little girl.)
