Hope I can really explain this: I have little pimple-like growth on the shaft of my penis.I've noticed it for a very long time now. More than 7yrs. It doesn't disturb me in anyway. But it's just there. Could it be why I use to have quick ejeculation at times?

This might help or not... but you should probably go to your doctor and show it to him... it could just be a "hair bump"... believe it or not a hair bump could be that stubborn and be there for several years. Is there any fluid.. like pus or anything that has ever come from this "pimple like bump"? Does it hurt? I think the best thing is to have a doctor look at it to be sure... I'm not sure though if that would have much to do with pre mature ejaculation...

Good luck, but please have it looked at.
