Something about the designs themselves... they just don't do it for me. Maybe it is the color combinations. That aside, the only content I find appropriate are in these two galleries:
http://www.sexsearchtgp.com/912/free...personals/1234
http://www.sexsearchtgp.com/910/blac...white-guy/1234
Mainly because these are the only two that could really pass as "amateur", and IMO, dating site hosted galleries should have that amateur feel.
