This is an old thread and I'm surprised I haven't seen it before. Anyway, I'm like the OP, I have a very strong attraction to black guys. I usually don't post about this because there are so many people who seem to think there is something racial or bigoted fueling this attraction.
I say; You like What you Like! No further analysis is needed.
Now, I don't know how or when this attraction started and I'm attracted to white guys too, but it was probably a matter of curiosity plain and simple. I moved from an area with very few black people to an area with a large black population during high school. I met some black guys at a party one night that were neighbors of a friend of mine. Pretty much, everyone in the neighborhood is friends, didn't matter black, white or whatever. That's how we started hanging around together.
As time went on I met more and more black people through these friends. Now, most of my friends are black and I'm accepted as a family member in several black families.
As far as the curiosity thing, well, everyone's heard about black dick and I developed an urge to see some of my black friend's private parts. Of course if you spend a lot of time with your friends and become close eventually you'll see everything you might want to see.
That's my advice to the original poster or anyone else who's curious like that. MAKE some black friends, hang around with them. Take my word for it; they're more than happy to make white friends and will accept you as one of them very quickly. Spend the night at their house or have them sleep over at yours. Go on trips and stay at motels with them, get drunk and have a good time. Believe me they are loads of fun to be with too!
