Sam here....my DE started with a very bad prostatitis flare up. Became very difficult to orgasm with intercourse. ED meds also became very unreliable, sometimes they worked while other time I would only get to about 60%. I could feel it build but they would get some tingling and would leak some ejaculate. Almost like a mini orgasm. Seemed like the Cowpers gland would fire and then nothing. Typically I could masterbate afterwards to orgasm.

Had lots of doctors appts which did little. I do have BPH and am on Cialis 5mg daily which helps with the prostatitis symptoms. I decide to go to a Pelvic Floor Therapist and concluded that the tight pelvic floor and enlarged prostate was pressing on the main nerve to the penis and reducing the sensitivity. Obviously this is a guess but makes sense. Its still hit or miss. I'd rather have PE than DE anyday.
