Is it normal that imagine myself as a stripper?

I've always felt alot older than i am. I make up and do sexy strip routines in my room when im alone.... Im a virgin and i've only ever kissed a guy. Im not a slut or anything, im an A*student in school so its not as im thick but when people suggest being a doctor or a scientist it just all sounds so boring im not really interested in academic :( I love the idea of being looked on by men and made to feel sexy. I bought myself some lingere and i feel more sexy and confident when i wear it. I could imagine myself being a playmate in the playboy mansion, or something like that. I've never told anyone about this, because everyone assumes ill just be a surgeon or something.
