Hello. I am a 27 year old male currently taking 200mg of Zoloft. I've had some odd problems with sexual actions lately. I have had vaginal sex in previous relationships. But since I'm not currently seeing anybody, I have resorted to masturbation to ease some of that tension. Except I will start to masturbate and won't keep an erection for long. It takes usually about an hour or so before I can finally climax. Would the high dose of Zoloft be the cause of that?
