I know what you are talking about joys. I was on Celexa for a year and a half. I often had trouble cumming. Not always, and escpecially in the beginning of my treatment. One thing in addition to trying different medications you might try is masturbation.

Women are told if they have trouble cumming, to masturbate and bring yourself to orgasm. A person can "train" him or herself to cum faster that way, or slower depending upon one's dilemma. It might not work as the cause of your prolonged erections are chemical, but you might find it works. Different people react differently.

I've been off the Celexa now for about 4 months and I have the opposite, I cum faster than I want! I got used to the prolonging effects and now-- spurt! I have found that my sex drive is way up though! I compensate to my wife with longer foreplay, but that is another post.

Good luck!
