Susan,
My point of view is a little different.
I lost the nerves (literally), and had/have no expectation of anything happening without my friend the Trimix needle. Being single, at first I was with the girlfriends from my "previous life". They tried to help, and yes, believe it or not, I can have an orgasm that is as good or better than anything I had before, with two exceptions. It is dry, and limp. Over time the girls dumped me, explaining that I was broken, and they were not interested anymore.
That will take a chunk out of your ego.
Since then, I have found, or my friends have set me up with, two personalities of women. First, the ones who really do not want sex anymore, and run when I bring up the idea of experimenting with the trimix (they really just want a neutered old man to take them to dinner and pay the bills, from what I have seen). Second, the ones who think that they are going to help save me, but give up and run when they realize that my PCa is not the "good cancer".
Does a dry orgasm bother me? Not in the least. Its all the rest that kills the ego and leaves me finally willing to go do the HT my oncologist is hounding me to start.
Maybe I'll meet a cute girl at the BOGO shoe sale, and we can go to chick-flicks together
