Looking for advice on fucking Thai shemales

[TripleTrouble]

Ok, so here's the story. I'm a young man who is backpacking solo through Southeast Asia at the moment and I'm going to be in Bangkok in 2 weeks for about 3 days. I'm thinking this might be my once-in-a-lifetime shot at getting some hot Thai tranny ass. However, I'm not exactly sure how to go about doing it.

It would be awesome if anyone with experience with Bangkok trannies could give me some tips on places to go (particularly which places to avoid in regards to STDs), how much to expect to pay, etc. Thanks in advance!
