The problem with having a porn-only sex life is that you might not be able to "rise to the occasion" when the time comes with a real woman. Real sex is very different, you get hard by passionate kissing and touching, you can do that with your eyes closed. You need more and more and more porn to get hard and stay hard while you wank. I love porn and wanking but I would strongly caution you against over indulgence and to diversify with real women. And whatever you do when you actually get in the bedroom with a partner - don't think you're in a porno. Most of the positions they show are very painful for women and awkward for men, designed to maximize the view for the camera. The penis sizes and body shapes are ridiculously out of whack with what real people look like. If you've been masterbating for years and years then you will have a hard time climaxing because you just won't get the tightness you need, it'll feel loose to you but the reason it does is because you've desensitized your penis. Remember when you were a young lad merely touching it would feel incredible but not so much now.
