I should start at the beginning: Radical Prostatectomy Jan 2018 at the age of 69. Positive margins on examination, rising PSA. 33 shots of external beam radiation at 2 grey each in August and Sept 2018. PSA was now undetectable. Used Vacuum device, trimix injections but not happy with results though orgasm was present (dry).
Had penile implants (AMS 700) in Oct 2020. This was the best solution I tried and had satisfactory orgasm. In the last year the orgasm response has weakened to the point of being nonexistent. Does anyone have a comment or suggestion?
