Is it normal to want to fuck really innocent girls?

I sometimes get the craving to fuck really innocent looking girls, not like underage or anything, just that girl in your dorm or down the street that's mildly attractive, but you get the strong feeling they've never actually had sex.

It's kind of like that urge to jump when you're in a high place or that desire to squish something when it's unbearably cute. I don't really want to do it, but somewhere deep in my subconscious my mind is screaming DO IT!!!

E.g. There used to be a girl in high school that I knew for a fact had never had sex and probably didn't even know what something like 'doggy style' meant, and something about that made me want to fuck her senseless, like ruin-her-for-other-men, crazy, fucked up sex. I never did, know it would be wrong, but I always wanted to.
