What do you mean "natural"? Since you're black I'm assuming your hair is dark and curly which will look hot, cute, and or sexy on you if that is how you look over all. The hair is just a part of the girl. If your hair goes with everything else about you it will be attractive to guys that are attracted to you.
As a black girl with huge natural hair, guys tend to love it. I've dated a couple of guys who say my hair was the first thing they noticed about me because they're not used to seeing black women who don't have really straight hair or some type of weave. I dated an Arabic guy who was damn near fascinated with my curl pattern and he was always all up in my hair, bouncing the springy curls around and seeing what weird patterns he could make with the tight curls. Overall, I've gotten a pretty good response from guys when it comes to my hair.
Seriously though, don't worry what guys think. Natural hair is so much healthier and a lot more fun once you figure out what works for your hair. I think that black girls ruin their exoticness when they straighten their hair. All of the ethnic groups have something that makes them exotic to someone somewhere. I think the thing that can make black girls exotic is our hair texture because no other group can get our hair to do what we can unless they're mixed. Same concept for Asian women who get eye surgery done on their beautiful slanted eyes
I think white people are a lot more accepting of the texture and look than black people. If anything, any ignorance you encounter will be from black women(who are snarky as any other women) and black men who are used to the weave look
I know natural girls that get attention from guys. if you're overall cute then it shouldn't be a problem. does that mean EVERY GUY will like it? no but it shouldn't stop you from getting play. even girls I know with very kinky hair (not just loose textured 3b/3c hair) get guys
