Actually, lucky you...since Thailand has some of the sexiest, most sensual and good looking 'shemales' in the entire world. Back in Vietnam days, an Air Force buddy and I went to Bangkok (the infamous Pat Pong Road 'red light' district on R&R, which back then was a regular Sodom & Gomorrah beyond imagining). After quite a few beers, we selected comely girls and disappeared into our respective 'cribs' with said girl of choice.
Somewhat later my buddy rejoined me in the bar and I asked him how it went. Although still pretty wasted, he assured me his partner was utterly fantastic in the sack.
A bit later, while I was getting another beer at the bar, one of the girls asked me what my buddy thought of his girl. When I assured her he said she was 'dinky dau', she cracked up and told me that his 'partner' had been one of their most gorgeous and talented shemales. I never told him, of course, since he probably would have trashed the place upon leaning this!
To this day, he probably is none the wiser! :))
