Yes, free. Thus it is basically a one night stand because no money is exchanged.For free eh?
First thing is that sex is not that common because that's not what those female clients are looking for; they just want to talk to someone and it stays that.i suggest you read the article before you write nonsense because the article clearly mention about $$$$$$$$$$$ for sex.
"sex" gets into the picture when the client is emotionally attached to the "host" and the host wants to provide something in return as a "customer service", but it is not common.
