I have PN in my feet and I use cymbalta, and I was wondering why this was happening to me. Forget a delayed orgasm, it's more like none at all. I thought it was the neurontin, because it kept the nerves from firing, and it was possibly doing it to my sex organ too. But it's probably the cymbalta. Brutal. How about losing an erection in the middle of the act - I almost got smacked because of that happening. Frustrating is right. Makes you wonder whether you should keep asking females out at all.
