Am I over thinking ?

I consider myself as a feminist person. I can't handle the normal definition of the roles in a relationship, like the guy is always in charge and the woman should listen to him and etc. Even, I was the one who asked out my boyfriend at the first place.

However, I'm super tiny, and my boyfriend is a tall sporty guy, which means he's way more stronger than me. Knowing this makes me feel crazy about him. I like to think about it when we're having sex or just goofing around. I like him to hold me so tight that I can't move. And it makes me a bit shy and feel great at the same time. But I think this is wrong and I shouldn't enjoy it. What do you think? Sorry if it sounds crazy. This is the first time that I feel like this in a relationship 😅
