Good on you, Axe.
I hope you have success with your choice of pump.
Most have an issue with pulling in the scrotum. The most expensive includes a guard to prevent this. Some have a cone which facilitates ease of attaching retainer ring on to the cylinder. Some have an outside sleeve that slides over the cylinder, which can be slipped down to push the retainer ring on to the penal shaft. Otherwise, the ring must be released with fingers, with a little difficulty. The more accessories included increases the price.
Some accessories can be purchased extra. All are pretty expensive.
(Bear in mind that warnings are given Not to leave rings applied more than 30 minutes)
I've never had an opportunity to use it for actual sex, only experimental. No partner since surgery.
I have little use for my pump.
I have tried injections. about $80 a shot. In my case, got only about a 5 out of it. A stronger dose may have helped, more bucks. Those are not uncomfortable or painful in any way as one may expect.
Good luck whatever your choice.
Agressive cancer, age 74, Jan. 2003, passed lots of blood, first symptoms. May 2003, Radical Prostatectomy and Urostomy. (Married less than 1 year, ended with this crap)
No signs of any recurrence. Just horny for 7 years and no natural relief. My desires have not diminished and docs have no answer. arrrggghhhh! (At my age? Thought it would be all over)
My best goes out to you and all the others here for continued recovery.
