If you mistreat a guy, chances are you'll get to meet a group of his friends in a dark alley.
In 15 years of living in Thailand I have never seen it...however I have seen many Thai on Thai fights and they never fight 1 on 1 basically cowards but if you are speaking of Jomtien complex I am sure the sissy boys there would hit you with their purse if warranted.
"In the land of the blind the one eyed man is king"
Many moons ago as I was walking along Jomtian complex, a sissy Cambodian bar boy caught my hand and brought it close to his crotch. I felt something proudly rigid and it was not any object that usually belonged in a dainty purse.
So where would I go in Pattaya of I'm after twinky little sissy boys?
