Are my pornogrpahy viewing habits normal?

Ok, so i've been a bit concerned about the porn i have been watching.

I have never had a girlfriend or any sort of sexual experience, mostly because i can do better then the girls i actually have the confidence to speak with (i sound like a prick but im actually not that bad of a catch, just a bit insecure,non-confident) and all the girls that get me all fuzzy and shit i dont have any confidence to approach or if they're a friend i just dont mention it. Plus, i went to an all boys school until last year so never really knew any girls.

But yeah, like all teenage boys i view pornography. I didn't start jacking it till i was about 15 (im 18 now) which i gathered is much later than pretty much everyone else. I used to just do it to cheap lads mag stuff but gradually progressed into hardcore but i still enjoy looking at a beautiful naked woman.

At one point, i got a bit sick of the sort of stuff i was seeing - even now, some stuff just doesn't appeal to me (cumshots, gross) but i dunno, the sort of shit that you come across on the internet, im scared im becoming desensitised.

I mean, i still do have fantasies about romance and meeting the perfect woman and just hanging out without doing anything very sexual, but when i feel the need to jack it, i find myself watching some pretty demeaning stuff, to the point where after im done i feel ashamed. Gangbangs? So gross. Rough blowjobs? Horrible. But i still find that shit sort of simulating. And im ashamed.

But recently, as in about an hour ago, i decided i have to stop watching this stuff. I have a pretty good imagination when im lying around in bed at night and enjoy the comforting, emotional scenarios but why do i always feel to watch that rough stuff? I used to justify it as just doing it for the fun, i wouldn't actually want to treat a woman like that - i still hold that belief but im worried that its just degrading my morals and changing me subconsciously.

I pretty much jerk off every night, even if i dont feel like it. When my hormones are playing about, its fine because i just need some beautiful naked pictures and i enjoy that a lot more, but when im just like "meh, cant sleep, porn?" i end up seeing stuff that i secretly enjoy but dont want to admit to myself. Im going to stop jacking it for a while just so i can jerk it do some tasteful shit (or just hopefully my rather innocent and sweet imagination) but i need to know was what i did all these months normal? Me and my friend were both baked the other day and i wanted to go home and jack off (because jacking off stoned is the shit) and he just transferred this movie he had onto my USB. When i got home and watched it i was pretty shocked by the sort of stuff in the video (it was called "Pornstars Punishment" if you need an idea) so that made me think that it was normal.

So, dear people... am i normal? Is it normal that i think i respect women and desire romance but still watch women gagging on cocks?
