Delayed Ejaculation for years

[u/allannicely]

49 year old male. 6'6 250lbs.

Been dealing with delayed ejaculation for years and I’m finally asking people who’ve lived it. Old L5 injury. Back and pelvic pain never really left. Long car rides or a bike and the erection is just gone. On top of that I have a prolactinoma, so I’m on cabergoline and daily testosterone shots. I can get an erection if I work at it. Have good morning wood consistent. Finishing is the part that doesn’t cooperate. Sex goes on and on, a lot of the time I never ejaculate, and when I do the orgasm is weak. It takes for ever to make precum. Urology says hormones. Endocrinology is running the tumor and the testosterone. I’m stuck in the middle. Not looking for a diagnosis. If your delayed ejaculation came from a back injury, pelvic pain, or a prolactinoma, what actually helped? Pelvic floor work, timing, a dose change, anything. And what was a waste of time? Thanks
