OH MAN. This is an old thread, but since the old Asian dick size fallacy reared its head, I thought I'd add a link to the discussion... bigasianman dot tumblr dotcom. Check it out and it becomes obvious...clearly there are some very well hung Asian dudes! (Google Keni Styles & Brandon Lee!)
All tall Asian dudes I've been with have had big (if not huge) cocks...like some as thick as a coke can. Whenever I'm with an Asian dude with a huge dick (or if I see photos like some on that blog), it makes me more pissed off that the stereotpye is repeated. I'm wondering if the stereotype developed because exposure to Asian dicks was in spas and lockerrooms where men tended to be older, shorter, & less nourished? As heights are growing across Asia (along with the number of calories/amount of fruit & fructose available, etc.), so is penis size and I wouldn't be surprised if the averages were on par with the west in a few decades. There was a story recently that the Thai government was calling for bigger condom sizes because they were too small for young men.
in addition, white & black porn tends to choose way bigger than average dicks to star whereas the only real Asian porn industry (Japanese) purposely choose small dudes to make watchers feel bigger...so you get really biased sample/false comparison (you'll notice they also choose older and less attractive guys, so we're not seeing even the younger, hot guys).
