Does size really matter? When having sex, how can men know whether the women reach organism or not? In other word, how can men know whether the women receive orgasm during sex? Is it physical appearance or emotion that allow men to identify whether the women reach orgasm?

These are a bunch of really good question that boil down to one question we get a lot around here: how do I know if I’m good at sex.

It’s a pretty common myth that a guy can always tell whether a woman’s had an orgasm or not. But in actuality, there’s no way to tell if a woman’s had an orgasm — the only way to know for sure is to ask her.

Women experience orgasms in different ways, and they can feel different for an individual woman at different times. So there’s no reason to feel intimidated or freaked out about asking if she’s had an orgasm — asking shows that you care about making her feel good, which is super important in being good at sex. In general, communicating about sex — before, during, and after — helps both of you understand what the other one likes and doesn’t like, which can make sex better and strengthen your relationship.

Now let’s talk size. The size of a man’s penis has very little to do with whether or not anyone has an orgasm. Women can have orgasms through different kinds of sexual stimulation, both inside and outside of their bodies. For example, a lot of women experience orgasm through stimulating their clitorises rather than penetrating their vaginas. Some women can’t reach orgasm through vaginal intercourse at all. So that brings us back to the whole communication thing: ask her what feels good to her. And while you’re at it, let her know what feels good to you, too.
