Men :: Surgical Impotence With An Active Libido

I am a 71 year old male. About 14 years ago, I had a high rating on a PSA test, which lead to a twelve needle biopsy. The results were rated as a Gleason 8 tumor. My urologist said the type of prostate cancer I had was very aggressive and that we needed to take some action. At that time, I was told my options were radiation and/or surgery. Prostate cancer had occurred in both of my Grandfathers. My father had not come back from WWII so I had no information on him. However, I had done some research into what I would do if prostate cancer visited me. I opted for a radical prostatectomy. Both my urologist and the pathologist believed that the surgery got all the cancer, and saw no value in radiation. As it turned out, I have never had much of anything to speak of on any subsequent PSA tests. Oh joy and rapture. I am alive, and doing well with one exception. Prior to the cancer diagnosis, my wife and I had a very active sex life. We had been married for over 25 years and had engaged in some form of sex on an average of twenty or so times a month. When my wife learned of my cancer, she asked for a divorce. Following the surgery, I was impotent and of course could no longer ejaculate. On the advice of a crusty older nurse, God Bless her, I learned that I could masturbate to a sort of semi erection and achieve an orgasm. However I entered a period of depression and when I finally found my way out of it, I could no longer achieve an orgasm. Following a discussion with my urologist, I tried some injections directly into the penis that was supposed to result in an erection, but it was not satisfactory, and the whole idea of sticking a needle into my penis was not very appealing. My doctor then recommended an Osbon penis pump which cost a couple of hundred dollars. When I tried the pump, it sucked my scrotum into the pump cylinder and slammed a testicle into the pump cylinder. It hurt so bad I threw up. The pricey Osbon pump ended up in the garbage. So here I am. My libido has always been very high and seems to be getting higher as I age. I am still very attracted to women and, have no interest in a sexual relationship with men. I don't really care for the company of men all that much and never have. Between the internet and satellite TV, I am bombarded with pornography. While I do watch a fair amount of porn and sexually explicit shows on TV, it does nothing to assuage my libido. I hate sleeping alone, and I hate the notion of nothing but platonic relationships with women. Over the years I learned how to do a satisfactory job of performing oral sex, however, even the ladies of my age still want sexual intercourse in their lives and to be honest, I would not be interested in a women who did not want sex. I have been so lonely for female sexual companionship that I have met with several prostitutes, and it is nice to be able to touch and talk with an attractive nude woman, but then I have to go back to my empty lonely place. Is there any way that I could reestablish the ability to have orgasms? Does anyone have an ideas or information as to how I could achieve an erection and failing that, how do I shutdown my libido?
