Of course it does.
You’ve never heard of playing Post Office??
nipples can help gauge temperatures as well…
Also they’re probably favourable to the female species. Breasts may feed the baby, but lets face it, natural selection means females with bigger breasts are more likely to breed because males prefer it.
Perhaps the same with females, although im not sure.
It’s only very recently (in the past hundred years or so) that large breasts have become fashionable and that’s in America. What’s favorable to one culture might be disgusting to another so natural selection hardly favors large breasts.
I’m curious–which male mammals don’t have nipples? My brother and I used to raise mice, and we tried to use the presence of nipples (“faucets”) as a sexing tool, but I’m not sure if it worked.
I was born without nipples, and I’ve never missed 'em. My wife can’t stand looking at other shirtless men now; they all look feminine to her, because of their nipples.
