I grew up in a multiracial family, and my first husband was African American. We had four children together. After our divorce, I married a "white boy" and he's my soulmate - but that has little or nothing to do with the color of his skin. I simply do not care what color someone is - I care about their character and personality (and it helps a lot of they're hot as well!).
My multiracial kids are dating and marrying whoever they want to. My oldest daugther married a white guy from the Midwest. My youngest daughter married a guy who is Sicilian, Puerto Rican, and Panamanian. My oldest son is dating a Korean girl. My youngest son is dating a white girl from Texas.
I say I don't care about color, and I DON'T. But there are some groups I've never "explored," mostly because I just wasn't overly attracted to them. For instance, I neer dated anyone Hispanic. Not sure why - except that most Hispanic men are shorter than me. Same with Asian guys.
I like manly men - and as long as they are very masculine and in a sense, powerful, I am not all that attracted to them.
When I got divorced I felt like a kid in a candy shop! Now I'm very happily married and don't long for those dating days, but it was fun while it lasted.
