I have always found it fascinating what exactly turns a guy on - for some it's a bum pic, others revealing spandex, yet more a hardon in a speedo. The list goes on and on.
As a suggestion, I thought it an idea to have a separate section where all members could post just ONE image of their most provocative image - and just see how it all pans out. I am sure it would be as diverse as we all are. But you never know . . .
