First of all Congratulations - the first step in fixing PC
I had problems and now use of pump.
It takes a little time to learn how to use it. Take your time pumping up - don't be too aggresive.
The biggest problem is pumping to hard and your penis hurts.
When you put on the ring, it can be tight - make certain you pick correct ring too tight it doesn't feel good.
If ring is too tight, then the feeling in your penis will be dulled and tough to achieve an orgasm.
I tried using two rings - Osbon d and c ring to keep it hard.
I have since found out the D ring alone works okay and even though the penis isn't real hard both wife and I achieve orgasm.
We tried injections so I know about urine discharge but urine and semen are still sterile so should not be a problem only though to peeing when you orgasm. Wife was turned off by that and injections (9yrs ago) weren't as good as now.
I would like to say every time is fantastic but its not. It will never be the same but at least both my wife and I enjoy it.
Just remember, my wife said the most important thing was that I am here. If I didn't have operation, I may be 6 foot under. Sex is what two people do to communicate their love. Its not necessarily the penis but other ways can be just as enjoyable to each of you. Its more work but you will do fine.
