@turtbean -- I had NS RARP on 06/2024 at age 70. I'm not a medical professional, so take my comments with a grain of salt. I had ED after surgery and that recovery took about 15 months to get back to normal, even though I was doing penile rehab (vacuum pump, low dose daily Cialis, on demand 100mg Viagra). Writing it now, 15 months sounds great. But during that 15 months, recovery felt soooo slow and it felt like it took forever to recover. The pump never helped me for sex, and I only used it at first for a few months for blood flow. I also tried to eat well, took vitamins, magnesium, L-Citrulline, exercise regularly, etc, to facilitate my recovery. I also started Kegels before surgery and continue the Kegels to this day to maintain pelvic floor conditioning. At this time I'm very happy with my ED recovery, but I still am on the daily 5mg Cialis (generic) and on demand 100mg Viagra (generic). I also still exercise, take a multi-vitamin, magnesium, and L-Citrulline. The pills don't bother me at all and since I had some ED and needed Viagra before surgery, I plan to continue to use them indefinitely. I don't really know if the vitamins, magnesium and L-Citrulline really help or not, but I think they do and so I hesitate to mess with success. 🙂 BTW, I believe part of my ED was that my penis just wasn't as sensitive as before until the nerves eventually woke up. For me, during my recovery I found I couldn't just "let the physical side" do the work. Rather, I needed to get "my head in the game" with more cuddling, romance, and foreplay. That realization helped me a lot, including reaching a point now where I normally am able to climax almost all the time we have sex. But I don't think I'd be doing as well if I hadn't made that adjustment (which I read about on this blog). Also, I had a verrrrrry patient and supportive wife. I've heard a sexual health doctor say anxiety is an "anti-Viagra", so it's important to have a partner who's trying hard to make it as stress free as possible. That also was a huge benefit I enjoyed as I definitely had a lot of anxiety whenever I'd make the attempt to have sex during the recovery time. During the recovery period (15 months for me) I never knew how successful any attempt to have sex would be. I found that stressful and my wife consistently did all she could to de-stress our attempts. I believe that was a crucial component of my eventual ED recovery (along with having had an outstanding surgeon). Best wishes.
