Seriously...nipples

Why on earth does a man need nipples?

Apparently boys grow nipples in the womb first...

Maybe its a gender indicator.

What can we really do about it? They're born with them.. Cut them off??

its so we girlies have something to play with too

Male cats have them too

So we can tell you girls it's cold out too. HA!

I want a real reason? I mean what function do they perform?

Does it Matter

Exactly so! Because we all start out as girls first in the womb; by the time the change occurs, the nipples are already there, they don't just disappear.

it's an equality thing...

Actually until the fifth month there is no sex organs. Whether it be nipples or other distinctions.

while we develop in the womb technically we're all male to begin with, then those who become female, do so, and the ones who remain male get stuck with nipples.

its true.

None. For males, they serve no purpose whatsoever.

They don't serve any direct purpose, men don't use them, it's simply easier to make people in that way, in an evolutionary sense.
It's only after about 14 weeks that a fetus starts to produce male hormones and starts becomming a 'boy', by that time it's already developed nipples so is stuck with them.
