I have never *actually* wanted to have sex with a woman

This realization hit me recently: I'm a 21 year old virgin and I have never wanted to have sex with a real-life woman. Let me explain what I mean: when I see attractive women out on the street, I glance and recognize them as attractive like most men would, but it's not concrete. I never feel true lust towards real-life women, only women in porn. I dated a girl last year who I was very attracted to; we kissed, even made out, but I never felt the kind of desire that would have led me to actually initiate sex. If she had been on the other side of a screen, I would easily have been able to fantasize about her and masturbate, but because my brain is hardwired to experience sexuality through porn and masturbation, being face-to-face with a beautiful woman didn't excite me the way it should have. Needless to say, my lack of sexuality disappointed her and was a major factor in our breakup, deservedly so. I've only now realized that it's not shyness, but my porn use that caused this confusing lack of desire. I know it's not too late, so I'm now fully dedicated to recovering so any future relationships I have can be more sexually healthy.
