you see it all the time...

if you're gonna go bra-less ladies (my favourite personally - sexy, yet doesn't give away the farm.)
then why are you so ashamed of the nips?

Yes, we're men and we like to look...isn't that why you wore the tight fitting tank top?
(yes, I understand that anyone can wear anything without being expected to be ogled at or made to feel uncomfortable)

I hate making eye contact with some who is suddenly embarrassed or possibly creeped out, if the catch me looking.

If we men had boobs of our own, we wouldn't look so much!

I don't think women actually understand the power of the boobs/nips.

Accidental nip-slips are the best tho!
