My advice here is clear. Yes, the Thai women Western men tend to get involved with may be similarly promiscuous to Western women, perhaps even more so. But there is a subset of Thai women who are virtuous and wish to stay that way until the meet their Mr. Right. Please, respect this. If she is waiting for Mr. Right, please don't lead her on simply to get her knickers down. You won't just break her heart, you could damage her psychologically and she may never get married because of it. Of course, if you take a Thai woman's virginity her family may expect you to marry her - and failure to do so may result in nasty consequences!
