Probably a very common problem. I've been dealing with it for years and it has fueled my porn addiction. I use it as an excuse. If she won't have sex with me, I can take care of myself. However, I was taking care of myself while we were having sex, before we were together and for many years before that. I don't recall being so addicted when I was a teen, but I also got in a sexual relationship when I was 15 and we had sex all the time. And, this was before the internet so access was trickier. I never wanted to go into a store to purchase porn, so I had to get it where I could.
But anyway, I'm really drifting away from your question. Yes. I'm dealing with the miss matched sex drive. But, I have to deal with my addiction first, then I have to start appreciating my wife and being good to her and hopefully things will change in the future.
I know this probably doesn't help much and I don't have any real advice for you except, take care of your addiction and once you feel that is under control, find a partner who you are more in tune with. I guess I could use that same advice.
