Sort of. 15 is generally "old enough" apparently, and treated like 18 is in america, so there are totally dudes creepin for teenagers. Underage or prepubescent you are liable to be straight up murdered and dumped. So it turns into the heb vs ped argument I hate.
What its really ground zero for is just outright prostitution including long term. You can pick up a hooker to be your gf for an entire vacation. Old dudes will basically scoop up a whore wife, and I mean OLD dudes, like they're marrying them assuming death will come in less than a decade.
Pattaya also has a ton of ladyboys, one of like 3 big spots for it. Bangkok has the surgery shit, so pattaya is the non dilator ones mostly, and its not like american trans. They're not fighting to pass or ever trying to compete with women, no trapping or tricking, totally 3rd gender. More like goth or emo, a counterculture. Same shit with 15yo in the gay and ladyboy side.
Actual pedo shit I think is way up north where its autonomous hill tribes and shit. Not 100% sure though. I do mean it, theyll fucking kill you if you seem like a little kid fucker.
