From my experience playing around, it's just part of the 'Primal Urge'. And partially a pushback on Fem 3.0
Amazing how easy it is to talk a woman into potentially compromising pics.
I had one friend whose views on sexuality precluded her from just fucking for the intimacy and fun but if I mentioned a camera, I could get into her pussy as soon as it was set up.
In fact I refused her. And I also refused to put any of the women I knew on the net where their faces would id them.
{Worked that into a few of my stories.. see 'The Lotto'}
Check out the 'amateur porn' sites, Lots of women like to compare themselves to Porn Stars, I think.
