I am a 51 year old male who is struggling. When I was a teenager, I masturbated almost daily. We were married 29 years ago, and have a monogamous relationship. However, our sex drives are completely different. I would like it daily, she monthly. It really was our only source of contention. Other than that, we have a good relationship. During our marriage, I would occasionally masturbate. I had no difficulty having or maintaining a strong erection until about 4 years ago. At first, my erection was not as strong, but I could still have one anytime. But over time, the frequency and strength greatly decreased. For the past 2 years or so, I can climax, either with my wife or by masturbating, however the erection is very weak. A year ago, I began taking Citalopram, and have noticed a significant drop in my sex drive. We have not had sex in over 3 months, nor have I masturbated. And it doesn't bother me now. Well, yes it does, or I wouldn't be posting this. But it doesn't bother me physically. Until 5 years ago, I would have  almost been unable to  go 3 weeks without sex, let alone 3 months. But now, we just go to bed and go to sleep. Our GP has spoken to both of us, seperately, about Viagra, and since she said she prefered I didn't get it, I agreed. Mentally, I still would like to have sex, but physically, I don't seem to care, and am almost unable. I do occasionally wake with a semi erection or can stimulate myself to the same state. I haven't had a strong erection in years. Does anyone have any comments or suggestions?
