I was on celexa for over three years, and while I did not have the testicular sensation you described I was practically unable to ejaculate, besides a remarkable lack of interest in sex. It does something that didn't seem to me to be altogether addressed in the disclosure of side effects that I saw. My cynicism aside, I would say to you that you can trust your own evaluation of side effects. You know yourself. Yours sounds like a genuine observation to me. Good luck with it all GreyGoose.
