My doctor put me on generic celexa(anti-depressent) after anxiety attacks. Along with being sleepy a lot, I noticed that I had to work at it harder to ejaculate and sometimes I cannot no matter how hard me and my wife go at it. I looked it up and this is one of the side effects of celexa. If fact, some doctors give celexa to male patients with premature ejaculation problems.

One side note: My wife has noticed that something is different, but have not told her about the side effect of the medicine.

Hope this info helps someone else
