Shaneris gave the best answer so far.
Some other things based on other answers you got - almost everyone gets their ability to have sex back to normal after stopping the antidepressant. Depression itself can cause problems, and perhaps that is the issue that other person is having. Don't rule out the possibility that the damage could be permanent in some cases, but I don't think there is any evidence of this (yet? if ever).
Cymbalta and effexor cause the same sexual side effects as the SSRI drugs - I don't know what Shaneris was talking about there, Any drug that acts on serotonin causes this problem, and SSNI's act on serotonin plus something else (dopamine? neurepinephrin? I am not sure). Supposedly fewer people get the sexual side effects with these drugs. I was affected just as much by Cymbalta and Pristiq (the new Effexor) as by prozac etc.
Adderall (amphetamine salts) is another "antidote" drug that can be tried. Also, women can try viagra type drugs. These things did not work for me, but I did not try the cyproheptadine. I am unable to take antidepressants without total anorgasmia, so I just won't take them, and I suffer in bipolar mixed moods hell continuously, and am suicidally depressed like 1/2 the time. You may have to make a choice, is what I'm telling you. I'm married, and I'd rather be in the hell I know, than lose the one positive thing I have left after having bipolar all these years.
