Anon, I'm a male, married for 36 years (to the same woman) and SHE was the zero libido one. After year after year after year of no sex, being told NO to intimate touch etc. I just gave up. But after sex examination I decided I WOULD have a sex life, with or without her. As it turned out all my research eventually got us to talking about the issue. We entered into therapy with a AASECT certified sexologist/coach and now we have a love-making session two to three times a month (enough for me NOT to go b'zonkers). Plus I had a radical prostatectomy four years ago. OK, I'm qualified to speak on this subject.
So, known factors that decrease sexual desire or erectile capability include: STRESS, diabetes, HBP, overweight, diet, and lack of exercise. Any one of these could be robbing him of his libido. Q: has he had a a physical exam including blood work in the past couple of years? What drugs is he on (MD prescribed)?
Next, and so important, is are you getting any therapy for your stress and emotional (men hide emotions/women launch emotions) disconnect from him? I know he seems to be the "broken" one, but what happens to him happens to you--so get into educational mode to learn about his dis eazes, and what treatments are available, Rx substitutions available, etc. But your and his "connection" emotionally is something to strengthen. I strongly recommend joint therapy for you with a AASECT (google it) sex therapist near you. You can "phone it in" with some, as well as in-office. But communicate, communicate, communicate with your BF. I can assure you that he is hiding his deep feelings of shame, fear, anger, guilt. It may take several therapy sessions for him to "own" his problem. Right now he can't begin to fathom how he can return to "normal" sexual feelings--so ease up on him--you can't "fix" him. Just re-affirm how much you love him, want him, value him, empathize with him, and want to stay with him and see this through. Continue to explore pleasing yourself,as well. Google Betty Dodson, she is the queen of female sexual empowerment and has a great website and advice. Love yourself. Educate yourself. Be an encourager to your man. Don't nag him. Express your frustration, within a therapuetic environment. When your BF sees that he can change and you'll go the distance with him, then the healing will begin--for both of you. I totally identify with your pain and loss of home. I persevered and its been worth it. Report back on this forum. GB.
