Bit off the beaten track, but I dropped into Urban Male on Sukhumvit 23 on the last day of my trip this year and was very pleasantly surprised. Not a big establishment, yet mid afternoon, ten boys magically appeared for me to choose from.
My chosen masseur was a fit dark skinned 29yr old (but looked younger) who was very friendly and intimate and got himself oiled up as he massaged my back, so when it came to turning over, his naked body looked fantastic. He was in no rush, said he hadn't cum for two days and subsequently came copiously to prove the point. Without being asked he joined me in the shower afterwards which was nice.
Total cost including tip was 2000 - worth checking out..
