I need advice.

I don't think I'm gay, because I like vagina a lot. But, I get so turned on when I see pics of a rock hard cock, and even more turned on when a guy covered in cum.I thought about hooking up with a guy but I never follow through. I'd want to top. But on the other hand. Bottoming looks fun too, I'm just too afraid of the pain for that.Any advice would be great. Thank you!
