Sexual problems related to Brain Tumor Surgery! I need Help Please!!

I am writing this because I had Brain Tumor Surjery in June 2003 . I have the following disorders:
Bi Polar
Osetosrthritis in my Hip and My Back
Substance Abuse/ Mental Health Issues
Chronic Pain
PTSD
Sleep Apnea
After which I was divorced from my wife I was abused by her for over 6 years sexualy, mentaly,emotionaly,physiacal volince, to the point now where trusting anyone is a big issue. I have a nother problem related to the Brain tumor surjery is that it was a pititurary tumor and they had to remove a lot of my pitituray gland to get to the tumor, and now I have only been with two women once and another lady later in 4 years, the two women were loversand one of them liked me a lot andwanted me to be with both of them. Most guys would have been happy I was scared to death and i was shsking so bad she thought I was having a sezure this is not really about sex but my reaction to it this has happened 2 times now with all 3 women of which 2 were at once. She grabbed me and wanted to stop the shaking finally after about 30 min I relaxed and I tried to make love to her I can get an erection all night but the problem that I am having is that I cant ejjaculate or come at all. even when I am alone so I dont even try and please myself it doesnt work. I dont know what to do and I think this is keeping me out of any new relationship my case manager thinks it will pass she told me that Iam a nice looking man and my problem was all up here in my mind and she thinks also that the medication may have done that but now they changed my meds I told her I dont have asexual partner now, so I cant even find out if I wanted to, I talked to my fem,ale roomate about it and told her I would need someone who would take me by thew hand and show me what to do like what would make her happy and what I would enjoy I domnt know I cant remember what I like I know that when I was with the 2 women and they were makling love it didnt turn me on.So I am looking into singles groups at churches and other ways I can meet someone to date. Im so fustrated when My roommate was dating and sexualy active. she knew that I was very unhappy and alone, she wasnt around at all and I got very depressed. now that she is home I am trring to get close again and we are like she never was gone now we have a very special friendshipn and she knows when I am hurting or need her. and I know when she needs my help. that was to be a gift from god. And I pray for help and I cabnt sleep some nights like tonight. My Cae manager asked me to do some homework and I did work on some of it tonight relating to Singles Groups Inn Churches in the Area. Tha may hve that sort of program. I also checked and downloaded the catalog for Santa Fe College here on Non credit courses that I may be intersted in so I vcan meet people there. All this I swhat I am trying to do to change my life as it is and meet someone which I can Have a meaningful relationship with. I was told to Focus on what it would be like if I was in a happy relationship,

If your equipment worked prior to surgery, and no longer works - I'd suggest you start by talking to your medical doc.

Good luck, Campy
