My girlfriend and I have been together a year (both in our twenties). I have also quit seeing porn for that long.
From the beginning she always insisted she'd only have sex after marriage. I was fine with that because I thought rubbing and oral didn't count (and it didn't, at least for the past year). I haven't been able to give her an orgasm for the whole time either, however.
The last few times we were together, she almost reached orgasm. Just when she's about to get it, she would stop. Then she would tell me how she feels an orgasm feels wrong - like the same kind of wrong as having sex before marriage.... Now she doesn't want to have any sexual activity at all besides holding hands and kissing, (but not even french kisses)....
Now that she's like this I just feel depressed. I don't watch porn because she's my girlfriend but she wouldn't let me do any of that stuff either. : (
Now I've started to google stuff like "should I watch porn".... grahhh
