I’ve been cancer free for 13yrs had seed implants and radiation therapy for 12 months and slowly after 3 years experienced dry organisms, limp penis, started with Viagra, worked for about 3 yrs, then every pill on the market, then Trimix which worked very well for several years. My wife of 31years had Diabetes and started going downhill and we quit sex completely in her last 3yrs. My penis stopped getting erections the last 4yrs. She passed 2yrs ago last November. At 77 I thought sex would never happen again because my Johnson had died, I found a wonderful 72yr old woman who was very understanding and we worked together to make sex happen. I started using the vacuum pump 4to 5 times a week and for 3 minutes at a time, started a Tri Mix but never got a rock hard erection. Finally I started a quad mix which along with using the pump 5 times a week and an understanding woman who helped me through massive anxiety issues worked out a way by standing upright it finally worked. My anxiety left immediately and achieved the first orgasm in 3 yrs. There is a down side with some discomfort and some pain but the outcome out weighs the pain. Good luck my friend
