Is it wrong to sleep with my foreign exchange student ?

Her English will improve dramatically if she gets pregnant. If she is of age, it is legal to sleep with her but it is immoral if you are married. And your wife will find out so be ready for that. In fact she may already know and trying to decide what to do.

It's wrong but boy it will be a hoot
That country is the biggest for sex industry she will be experienced and ride you like no one else
Get ball deep in her while you can bro!

You have a wife, stop whatever you're doing.

If it's okay with your wife, fine. If you didn't think it was "wrong" you'd go ahead and clear it with her.

How can you betray your wife, betray your position of trust in acting as host to a foreign student, and abuse a minor child who speaks little English? And it's criminal - statutory rape. Scumbag!

That's appalling, and also illegal as a quick browse of the hosting rules for international students will confirm.

It doesn't matter what's legal in Thailand, it's what legal where you are. And what you're thinking about is illegal.

It's wrong.

You're an idiot to risk your marriage and your life for a meaningless fling.

Well you're the one who made your wedding vow, so - you work it out.

of course its wrong... teh bad news for you is that she is more than likely to blackmail you.. so see how that goes..
