I see a lot of profile pictures here in which the men (and only the men) show their erect cocks.
Women would never use their vulva as a profile picture! And they think dick pics as a profile are stupid - and rightly so! If you want to show women a body part in detail: Show your hands! Women are much more interested in what the hand that might touch them one day looks like...
Did I want to meet a woman who shows her vulva in her profile picture? No!
