I don't know about that.
Most guys I know actually pick someone outside their own race as their favorites...however; most end up with those within their race many times.
I just like women in general, any race can be beautiful, ugly, sexy, smart, stupid, boring, etc. Never slept with a black woman, but had one naked with me once. She didn't think it would be a good idea since we didn't have protection. She danced naked for me though and that was pretty awesome. She liked big black dudes though and came from a very traditional african-decended family. We met in school together, and even once I had something ready to go for the 'date'...she just danced around more. I finally told her I was not for her obviously and she should have just told me. We didn't stop talking to each other that term and surprising it was like business as usual in class. I don't know which class it was though

, it was some cannon fodder you have to take though...none of my critical classes.
I have been married to a white woman (I am white), and now a Japanese woman. I have been with several asians prior to her (filipino, korean, vietnamese, taiwanese), a lot of hispanic/latina (considered an ethnic group and not race though, no mexicans or guatamanians) and white girls (I can picture most of the other women I have been with, but the white chicks sort of blend in together to me...some still haunt me though in great memories we had at the wrong time in our lives), but never any indians or those arabic/egyptian (although these people look very different to me, they are not considered a race) other than just dates and maybe a kiss although I find them beautiful as well...those I dated had striking faces and a great lower body.
I don't base my mates on what they were born into. I am not going to say it's only what's inside that counts (unless it's me

), and I am not going to say they have to be someone that would win every swimsuit contest either.
I like a fun and cute woman, someone I can talk to...someone that can be sexual and someone that can be practical as well.
If this relationship doesn't work out, I doubt I will re-marry. That's another topic though...there really is no upside in marriage other than those talked about in fairy tales which at least UNCLE SAM burns en masse.
I hope one day race is something that gets discarded once everyone's genes mix. I am sure there will still be impoverished areas that will look different though.
