Hi Jensitive22, I agree with the others who urge you to discuss this issue. Try to push past any embarrassment, if that's part of the issue. I also heartily agree with Miguel'sMom that your therapist could also be of assistance. Either way, it is something I, personally, would bring up with them first alone. If they then think inviting your husband to a session may be helpful, do consider that. They can help mediate and educate.

Lack of sex drive can definitely have causes other than medications. I also know there are some partners that can be quite understanding (as buddha1too stated) and those that take it much harder. I take oodles of medications, and though my middle-age has brought a slight reduction in sex drive, I don't think my current meds do. It's actually my husband who has some issues, and ones beyond his control. I did mention this issue to my therapist, my gynecologist, and latter my old psychiatrist. Even though the issue lies less with me. But it is a significant issue for couples. I think your husband is in a mild panic and perhaps over reacting. I do get that a bit.

I had the hardest time mentioning this to my old psychiatrist over the others I mentioned. Mostly because I had a transference love for him. I did it anyway. Sinxe my meds weren't an issue, his advice didn't focus on that. Yours can, unless you are happy enough with your status quo. If so, that is a more significant relationship issue than a med one, I think.
