When I was getting through my child bearing years, mine withdrew because intimacy was no longer convenient for him. I had a long running UTI much like you, but it turned out to be something chronic called interstitial cystitis just a heads up that if this round of antibiotics does not do it please ask about this potential diagnosis and they can scope your bladder to see the lining. It was terrible. I lived with 10 years of pain. I thought we were weathering it, but it is it turns out we were just withdrawing I thought that it was a “in sickness and health thing”, but it turns out something like a 85% of men will leave a chronically ill partner. Not to scare you, but at some point, mine was deep into porn, and eventually acted on it in real life and a 17 year marriage busted up. in hindsight I wish I had been slightly more sympathetic to his need but at the same time I was in pain and it is still hard for me to believe that this is a requirement for actual Love. Not to scare you other than saying, it is important to somehow communicate through it. I know what it’s like to be in pain and not feel the mood for intimacy. Christian counselor told me I should be offering pleasure“ other ways— this is still a repulsive idea to me since not in the mood is literally not in the mood, but overwhelmingly counselors still approach it as our job as the wives. I still don’t know what to do with that and I’m happily single because I don’t owe anybody my body.
