Everyone knows that the head of the penis is the most sensitive part, but how much it affects our ejaculation? When we are about to ejaculate, almost anything we do to our head can trigger ejaculation. Even squeezing the head can make us ejaculate, and when it is inside a woman it is squeezed a lot. I mean, everyday there are a lot of factors discussed at this forum that can contribute to premature ejaculation: APT, pelvic floor imbalance, hormones, histamine, vitamins, mental aspects, etc. Probably every one of those factors have an effect, but why when we use a numbing spray in the head of the penis we can last considerably longer even when all those factors remains the same? If we can make it less sensitive, will it help? I think that maybe if we do our edging focusing only on the head and stimulating it in several ways (for example twisting the hand on it like when we are shining an apple) it will be less sensitive and help us last longer.
