Now i have zero experience with lady boys in Thailand but I do have experience with t girls(trans) here in the us. T girls are not masculine looking or cross dressing men. They are on estradiol and progestrone and they also do many cosmetic surgies(everything that you can think of and maybe some procedures you are not aware about). Many of them are high class escorts and make bank and fund their cosmotology and transformation through providing services to gentleman(that or suger daddies is the only thing that can make that kind of money. They litterally have to in order to fund the procedures). Now the t girls who I've got head from and one I banged were all really feminine and had banging bodies with big round asses, big tits, long hair extensions, and all the work done. The one I banged I met her in the streets so I got that for free. The other t girls I had to drop a bone to get some head and Im a good looking dude, lean, and muscular but you got to meet them outside their occupation or else they wont service you for free even if you look like Brad Pit they are about that paper.
Regarding thailand I have heard that the ladyboys transition into girls at a young age before puberty and they get on estradiol and progestrone stack and become feminine sometimes they may even remove the cock and balls. I would rather fuck a vagina then asshole but sometimes a man wants to pound some feminine ass or cum down the throat from a good blow job of course she has to look attractive and feminine but I don't have experience with lady boys as I have yet to visit Thailand but when I go I will for sure look the baddest and most feminine lady boy and dick her down and get sucked up like a slurpee lol.
