Thanks to this thread and a couple of inputs in other threads, I reserved some time with a Japanese muscle boy.

I had a mediocre experience. HIs body looked just like the pictures and the face was good, a bit rugged as Hadakanbo wrote about his guy. (I'm not into the Japanese pretty, skinny boy type). The shower part was fun so I started off happy. But it was soon very apparent that he wasn't up for me. Then he started trying to get me off as quickly as possible. He claimed to be bi but I think he was straight. I could tell that he smoked, which I figured usually comes with the territory in Japan (I usual ask beforehand with providers in the US.) . Now I can't get metallic taste out of my mouth. Blech. I'm still glad that I did it and appreciate Hadakanbo's sharing of the info.
