Is it normal to like 30+ year old women?

I'm 18 and into 30 year old women. They look very mature and seem to be good models for girlfriends. I heard that during sex, they know what they're doing and know what they want which really gets me sexually aroused. I wonder if they would really abuse me or not. I find it pretty attractive for them to have a little wrinkles on their face and to express their views on things.
