personally I love Asian guys, having fucked/been partners with Asians, African, Caucasians I seriously prefer Asian men - but southern Asian guys from Thailand and Philippines.
Whilst there are many 'surveys' of varying accuracy they all agree that there are MINOR differences in average dick size, and just as there are outliers or non average guys of all races the same is true of Asians.
That said, I've never found an Asian more than 5 inches, and having had a few Asian partners and asked them about their experience of other Asian guys (if they've actually slept with any) they all say they are much smaller than white guys.
But whilst they MAY lack in dick size, they have beautiful skin, perfect naturally slim bodies - and if you're lucky to find a really buff Asian as I have wowser, very tight and tiny ass, tiny holes and absolutely amazing lovers.
Asians all the way for me
