I started out on rentafriend.com and someone i met from there mentioned CC. Rentafriend is a bit different no cuddling or even hugging of any contact really of any kind usually they just do activities together for base price from $20 to $50. Movies dinner working out going to family events etc.
I've met some good friends on there that still friends with to this day. I don't see it as competitive to this site as they are very different in nature and beneficial in their own way.
