How long should the penis be to give a woman an orgasm?

Penis size has very little to do with whether someone has an orgasm.

Most women and people with vulvas don't orgasm from penetration alone. The clitoris, which is the most sensitive part, is on the outside of the body, near the top of the vulva. It's not deep inside the vagina, so the length of a penis doesn't really come into it.

The part of the vagina that is most sensitive is actually the first few centimetres near the entrance. You don't need a long penis to reach it. Most of the internal vagina has relatively few nerve endings compared to the clitoris.

What actually makes a difference is communication, paying attention to what feels good for your partner, and not rushing. That's true regardless of anyone's body shape or size.

If you've picked up the idea that bigger is better from porn or conversations with friends, it's worth knowing that this is one of the most common myths about sex. It puts unnecessary pressure on people to worry about something that doesn't matter nearly as much as they think.

Most women do not orgasm from a penis going in and out. The clitoris is the most sensitive part, and it is on the outside of the body, near the top of the vulva. It is not deep inside. So the length of a penis does not really matter for this.

The part of the vagina with the most feeling is actually the first few centimetres near the opening. You do not need a long penis to reach it.
