Why do some men have flat, disk shaped nipples, while other men have perkier, raised nipples. I assume perkies are more virile.  
Which are more common?  
Seriously! This question has bugged me forever.

Men’s nipples change when stimulated, just like women’s.

My nipples are always perky and pointy. When I’m cold or aroused, they get hard, that’s all. Many male nipples I’ve seen are flat (don’t think I’ve ever seen cold or aroused male nipples, though). My nipples are also exceptionally small and extremely sensitive. I can’t touch them, that sensitive. I wonder if this has something to do with the 1/2" diameter - nerve ending density through the roof?

I guess it is for the same reason some women have perky nipples and others have flat nipples.
