Apoligies if this is unsuitable for the forum, but it's been a long-running wonder of mine why when, after masturbation, it takes a few hours to be turned on by something again, even tickling! I assume this happens to others (I can only assume as I've never spoke to anybody about such things!) but can anybody give a scientific explanation, or just simply a simple reason, why. Am I being really stupid and naive here or is it a fair question?! Please get thanks to me, thanks.
