Hi Cosmic Joke,
When I was younger masturbation as a guy was just a 15 to 20 second affair, I honestly couldn't understand why people were so interested in sex. As I tried to have relationships I began to understand that the intimacy was a beautiful thing but not the intercourse. I didn't have a proper orgasm until I was 43, the story of how that came about is a little weird.
Until a few months ago I was in my first relationship. We considered it a lesbian relationship, Gabrielle is trans-female, 7 years post-op. The problem was that I got nothing out of the relationship except the intimacy, I really didn't like having my genitals being touched. We tried something special.
I would meditate for maybe 10 minutes then concentrate on picturing myself as a woman in my minds eye. Gabrielle would then start to make love to me, the difference was that she would, with a low steady voice, describe, when possible, what she was doing to me. When she came to my male parts, she would describe touching my female parts in my mind. The touching would be closer to how someone would arouse a woman. She would pull back my foreskin and rub my glans as if it was a clitoris. Over the next 10-15 minutes I would climb onto a plateau of arousal like a woman and then peak to orgasm 4 or 5 times in the next 10 minutes. Quite different to the 15-20 seconds of disappointment I was used to. Ooo I'm getting quite worked up writing this stuff down.

This only worked 3 times and I have always thought it was some kind of hypnotic suggestion, but I think you'd have to be trans for it to happen.
I don't think my brain is wired to accept stimulation as a man.
My journey to where I am now has not been a nice one, physical abuse, sexual abuse, drug addiction, self-harm, suicide attempts and severe mental illness. If this thing is causing you pain then please deal with it, go talk to professionals, you ain't nuts Flower, try and sort it out in a good way, not badly like I did.
You take care Babe, keep kicking , you'll get there.
Luv & Hugs going out to one and all.

ps. we call every one where I'm from "Flower"
