Is it weird that i have these fantasies at 17?

Hello!! (17F) here, lemme explain Rq, i live in a place where sex is allowed at the age of 15 and up, so everyone ik already had some experience, while i barely even held someone's hand, i was never in a relationship or even had a first kiss, but for the past few months, ive been having fantasies and needs that make me feel SO embarrassed, the main one's are that i only feel attracted to older man, propably due to my fantasies of being dominated and put in place and etc, i feel like such a damn loser due to these stuff and i don't know what to do, are my feelings normal or am i just genuinely bad in the head for having almost everyday needs like this??
