@nothingness Short answer: No. Longer answer: Two other gay torrent sites I follow occasionally have collections of still photos (in .jpg format) from "modeling magazines" of semi-nude solo muscular Thai guys, mostly in their early/mid 20's, but never showing a full naked penis. Usually it's partially disguised by some very flimsy gauze that leaves nothing to the imagination. Often these torrents would have a few "behind the scenes" video clips showing the model fully nude, and sometimes fluffing himself to orgasm.
Perhaps they are taken down by the copy-holder's request or some other reason. Thailand, while seen as a "sex tourism" destination, has rather strict laws about online material.
I have downloaded some of this stuff, and generally don't keep it...but the next time I do some archiving/purging and I find some, I'll let you know. I could either post it as a torrent or sent you a private DropBox link.
