I specifically target them when I man-hunt online (for sexual encounters or otherwise). I'm not Japanese but I can speak Japanese pretty well, and I've never had sex with non-Japanese people before. (I don't live in Japan tho) It's kinda hard to find young japanese guys who are dtf outside of Japan, it's usually guys in their early 30s or so. I'm currently dating a 22 year old Japanese guy. (Not going to elaborate on his 6-inch dick tho)
The smallest dick I ever had was a 19 year old Japanese dude who imo was pretty cute. He had an un-retractable foreskin and honestly it was so small that I could fit the whole thing in my mouth without feeling any kind of discomfort and I swear I could hold its entirety with one hand, it was so tiny. He was also super sensitive and the first time i gave him a 'handjob' he came in like 20 seconds tops, not to mention that I was only touching him from on top of his underwear. Not even sure that counts as a hand job.(Makes sense that he was a virgin) I let him tittyfuck me once and his dick sort of disappeared between my boobs, I almost laughed at it.
