I am a Black male (Zambian-Canadian), age 23.
In my teens, I was obsessed with dark skinned Black women. I rarely ever thought about White women sexually (I almost never thought about them romantically), I rarely ever watched White porn (if that's not too personal). I don't want to sound arrogant but there were a lot of White girls who told me they were attracted to me but I didn't care. I was completely indifferent to White women that most people thought were unbelievably beautiful. I was 'neutral' when it came to non-Black women of color (I guess this is still mostly true, although there are very pretty Indian, Asian, Latino etc. women). In fact, there were times when I was bored by most light skinned Black women and only chocolate skinned women caught my eye.
Something changed when I was 20/21 and I began to look at White women differently. I don't just mean sexually, I mean romantically. For a long time (and I hate to admit this), Black women actually bored me and I had to force myself to be attracted to them. I've always been very 'proud' to be Black and even now, I wouldn't actually consider dating or having sex with a White woman (no matter how much I liked her). Now, sexually, I'm equally attracted to Black women and White women but romantically, it's easier for me to fall for an attractive White woman with a nice personality than for an attractive Black woman with a nice personality (most of the time, not all of the time).
I kind of hope this changes because Black women (specifically African women) are the only ones I'm interested in actually dating. I have interests (ie. veganism, science etc. ) that Black women are stereotypically not interested in and I live in a predominately White neighborhood, that might have something to do with it.
