Strict Bottom?

I identify me as a gay bottom, maybe power bottom. I don't have much experience with gay sex but I was always fantasizing about being the bottom in sex the submissive one and I think this is what I want in sex. In real life I'm not feminine at all quite the opposite. But I am afraid that there is something wrong about me because I don't wanna use my penis so much. sometimes I think I'm just afraid or there is something pshycological behind. Please tell me what you think because it is a big fear of mine.☺
