I never got why on dating sites men were always so eager to send dick pics - it's like the least attractive part of a man's body.
One guy (on finding out my job etc) said he was making himself look intelligent for me, and sent me a photo of his dick wearing comedy glasses and a moustache. That was actually reasonably amusing, but all in all, a dicks a dick, and I really don't need to see anyones bar the person I'm sleeping with. It's why I never got the attraction of male strippers either - who wants to see some bloke stood there helicoptering?!
