' without any proof or way of really knowing the impression i get is that in Thailand there is no or very little forced prostitution '

In terms of girls or boys being kept under lock and key and then sexually used against their will, there is no evidence that I've ever seen.

However, I do know of bars that are police owned, and appear - although I've no absolute proof - to be staffed by girls who are working as an alternative to doing jail time. It's been noted that these girls do not have their ID cards but do have some papers issued by the police. As the papers are in Thai it's not clear what exactly they say, - it's speculated that they may be a licence to be out and about in certain areas only.

This is close to being a 'forced' situation. It is also noted that in establishments primarily catering for Thai customers, the proprietors order their staff around as though they own them - it's not clear why the girls put up with that - the impression is given that they have no choice..

I've never witnessed anything like that in the gay scene however..
