Social networking sites are way better for this than dating sites i reckon, Tagged is good, i was a member of that and found it a great way to hook up for no strings sex, facebook or "fuckbook" should i say is the very same. Although, it does help im very young myself, plenty of fucked up pervs on that too looking to get with 18yo's! Jeez you mess it up for genuine slags like me that wanna get laid
