Didn't really ever have an issue, even when I did watch porn and fap every day. I stopped doing it to make real sex better, I can see how it could dull you to the point of not getting it up.
I used to get hard by just thinking of fvcking a woman, now it's a bit more normal. I get hard when kissing my girlfriend and until a few minutes after I orgasm, it's like this every time now. I notice when I'm a little more stressed or tired I last longer, but when I do come it's more intense because I worked so hard at it.
I have watched porn around 4-5 times during the relationship, I could just as well fap without it, does nothing extra for me. I very rarely fap, first reason being I have no need, second reason being that it's inferior to good sex with a woman anyways.
If I'm going to give you any advice it's to stop watching porn. It's something to at least try, give it a good chance and don't watch it for a month. About the fapping you can try stopping that too and rather spend your energy finding and having a woman to fvck. If you're running dry and can't stop fapping then at least fap to your imagination, realistically visualize what you'll do with the next woman you fvck. You might think up some new things to do in the process and find what turns you on, which can be helpful the next time you have a woman to fvck.
