Postprostatectomy, is there any sexual release like nocturnal emission

I had a prostatectomy and was impotent even before the prostatectomy. I have never successfully reached orgasm by masturbation while flaccid, even before the prostatectomy. Injections don’t work for me due to venous leak. I sometimes wonder whether I could still reach orgasm from oral sex, but have never tried since I am also incontinent. As a result, I am preoccupied by sex all of the time without any release. Rightly or wrongly, I always assumed that nocturnal emissions in my youth were caused by the prostate being swollen with semen due to sexual inactivity. My radical prostatectomy removed not only my prostate but both neurovascular bundles and the right and left seminal vesicles, so of course there is no longer any buildup of semen. I have had sex dreams post prostatectomy but of course never woke up with wet underpants due to no longer ejaculating. I am wondering whether the buildup of sperm in the testicles causes any sexual release comparable to nocturnal emissions to relieve sexual tension for prostatectomy patients.
