I'm very attracted to black men, but I'd never say they're the only ethnicity I would date. Here are some of my reasons:
--They more commonly have a body type I'm attracted to. Well built with defined muscles all around. Not all girls like muscles, I really do. Also the dark features. I tend to go for tanner guys of any ethnicity.
--They tend to be straight to the point when it comes to attraction. If they think I'm hot, they'll come over, tell me and ask for my number. I'm a confident girl, so their confidence drives me wild.
--They tend to be very masculine and have a certain "swag" like MeuAmor said. It's a little indescribable.
Overall, while every guy is different and it's impossible to judge an entire group of people based on race, there are a few traits I've rarely seen in all of the black men I've dated. They were never insecure, desperate, afraid to talk to me or afraid to be a man. And they usually have a body type I find attractive. Like I said, it's impossible to judge an entire group based on race, but those are my findings. Now when I run into guys of any other race that demonstrate those qualities I find attractive, I'm all over them too!
