I am currently taking Zoloft for the past 3 years. I want to change to Wellbutrin because my research shows it has the lowest effect on sex drive. I am not able to have a climax and think it is because of the Zoloft. I have no problem getting an erection, even at 79, but not able to have the climax. Anybody reply on their use of Wellbutrin in regard to sex drive? Thanks so much.
