John, I’m happy for you with the results you described. Had my surgery in 8/24 and 2 yrs younger than you , got a pump months ago with little luck and now going thru hormone treatments and radiation I get too frustrated to try the pump every day. The ring hurts and the few times I was hard enough for sex , the pleasure that I dream having again wasn’t there. I was lucky having sex several times a week for 40 yrs with a younger wife who would have been happy with once a week wanted to please me. Can’t help but think she is not suffering as I am . When treatments are over I will try anything and everything to feel normal once again including injections. Good luck
