I underwent a radical prostatectomy around 15 years ago (when I was around age 50.) I've been impotent ever since. I don't blame the surgery alone. I think it was probably a combination of the surgery, my mental health struggles, antidepressants, & other stuff. The only E.D. med I ever tried was "Muse". All it did was make everything swell up & ache. I don't have much of a sex drive left anymore; and I'm glad to be rid of it. So I really don't care that stuff doesn't work.
