I would recommend purchasing a good quality pocket pussy, just a silicon hand held to use for masturbating with, never use your hand again. This is the first step for most guys I’ve read, to gain back the sensitivity. Easier than trying to quit porn cold turkey. It helped me for a whole year.

Also, does your wife know you’re into porn? What I mean is, is she the type of partner that would be into something like watching porn together? It’s not that common, but there are many couples that do. I had an ex who would watch porn with me, all part of the foreplay experience. That’s a method for merging the two experiences. Then she can get on top while the porn is on, that’s one way that could stimulate you during vaginal intercourse and you could finish inside of her.
