Is it normal that i like asses so much?

I'm a girl, and I have a huge thing for asses. Doesn't matter if its a girl's ass or a guy's. (Though, I prefer girl asses) I like other things but asses are like my biggest turn on. My boyfriend lets me touch his a lot because he knows I like asses so much. I just feel a bit embarrassed about it because its so weird to me. I don't know any other girl like this. Then again, its not like someone would randomly tell me their fetishes. Lol.
