A lot of online dating site data suggest that Asian (and Indian men) are the least desired men in the dating scene.
This has always blown my mind given the huge contrast to how well Asian men (in general) do in the professional world.
After thinking it over, IMO it boils down to:
1) Confidence (lack thereof)
2) Self Image (Asians are generally more obsessed with superficial things which isn't aligned with masculine attributes Western women are attracted to)
3) Height (hard truth, we're generally shorter and it's a physical filter for a lot of women.)
Other than 3) above, everything else is in your control. Even if you are vertically challenged, you can still live a lifestyle and maintain a mental attitude that is attractive to women.
I'm Filipino, about average height (5'10,) and moderately successful in a corporate finance job, and I'm totally satisfied with my sex life. Not that it matters, but for perspective, I've slept with 5 different white women so far this year lol. I attribute it to just being confident and living a lifestyle that is fun and engaging.
I hate when Asian guys blame any dating/love life issues on their race. It's a cop out. There should be no reason for race itself to be an inhibitor to getting laid. You are playing yourself if you think it is!
