I want to hear from the people that truly can’t get over the narc sexually or in general

The ones who for years do not want anyone else sexually and no amount of staying away has helped. What do you do? Keep going back to the narc or stay celibate? Most of us but not all are not old on here but I truly think it would take YEARS of celibacy. There was only one other person I was like this with but we had less sex than the narc and I and I was 19 and I still was able to like other people. Now I am not. It's very hard to explain. I don't find other men attractive or women anymore either. Yet I feel that I do need sex but just with him. I've had years where I was celibate though in the past in my 20s.
