At the risk of never being found out my real idendity I will put my 2cents in.
My SO just recovering from prostate cancer, has tried it all. After Viagra, he used the injections. They worked for about a year. He didn't mind the injection part into the most delicate area of a man's body, but, the window of opportunity isn't all that long. Also, the problem of having to go through the preparations can be a turn off for a partner.
The injections are the last option so now he is in the process of having a lift station installed. There is a lot of information on the web about this handy devise. Go to
www.penileimplant.org/index and check out the videos of the whole works and how it is manipulated. The doctor's name is Dr. Eid.
When I was caring for patients, I had several that had had this procedure, they weren't too uncomfortable (as compared to back surgery).
Don't be afraid to ask about this. You would be surprised as to how many men are walking around with this problem and, how many have the pumps.
Good Luck
