I'm in the same boat. I'm a chubby white guy, with a big, round ass, and black guys love me. And I tend to be attracted more to the brothas these days too, not so much because of race, but because I'm just not that attracted to the types of white guys that are into me lately.
Now 10-20 years ago, when I was a young, skinny, twink, with a tight round ass, I very much prefered the studly white guys & silver foxes I would attract. But to be fair, I didn't get nearly as much attention from the brothas back then. So my tastes have changed to suit my options, I guess.
How do I feel about being desired for my race (and fat ass)? Greatful.
I miss being a sexy young twink, and all the attention it got me. I loved how much I could turn guys on back then. So I'm very greatful for the attention I still get now, despite having lost the battle of the bulge. And I'm greatful that I can still attract guys that I'm attracted to as well.
