Unfortunately, there is no perfect site! I would suggest that u read the reviews on here and try to pick a site that u think may be a fit.
There are a some sites that I think cater to girls that are exhabitionists and mostly perform for peanuts or free but that's my opinion. Even after doing this for almost four years, before I log on, I check the site to get a feel of the "vibe" at the time.
It's just not the site but the time, season, major sports events all are factors......try a site......give it a chance but don't jump too fast!
