Dude! Are you even qualified to give a 'massage'? Chances are, your PT is, and so are the Thai Coaches you see doing it? Does your PT ask you to strip? If he does I'd question what his intentions are dude, make sure he's not slippin sum rohip in your water while you train
And the fact its okay for you cos he looks foreign makes you sound like an out and out fag!
And who touched you when you were a kid for not to have found it wierd back then, serious issues la!
