Has anyone every had a nocturnal ejaculation after surgery? I know the prostate and seminal vesticules are gone and no fluid or pressure can build up there but the testicles are still producing fluid and seems like that would be enough pressure to produce a nocturnal ejaculation. My testicles get so hard sometimes from pressure build up that they ache and then I have an ejaculation and they are all geared up to empty out but can't because the vas is tied off so they ache even more. I had a nocturnal ejaculation about a week after I had my surgery and the catheter was still in. I woke up in the middle of the night having and ejaculation but of course nothing coming out and I thought, is that what a dry ejac. feels like? I had surgery 8 years ago and that is the only nocturnal ejac. I have every had since.
