My husband has been on different antidpressants for nearly 10 years now and I've had to deal with his lack of sex drive and it's been though. He's now on Prozac and it is working well for him. He takes Levitra before we have sex so he can stay erect, but it is a rare occasion that he climaxes. He mainly had sex just to satisfy me, because he knew how important it was to me. Now with me not being able to climax - it's really bumming me out. I'm not ready to give up on it, I'm thinking of cutting my Lexapro down to 5 mg on the weekends to see if that helps.
