Because they rock, are fabulous, so beautiful and just incredibly sexy !
I have had the MOST incredible experiences with my ATF Stella James - in particular, but also other Asian and local AA girls I have reviewed, like Seeking ~P, Jada Marie, Lena Duvall and Armani. Among them I have found some of the most intelligent, confident, sexy and exciting women I ever met.
Maybe part of the attraction is that a guy doesn't prefer a woman who looks like his mother or his sister. There is a natural, healthy instinct to mix genes.
