Myth 3: Some women just can't have orgasms.

While there are a percentage of women who have never had an orgasm, there is no evidence to suggest some women are incapable of having orgasms. There are two reasons why some women have not had orgasms in their lives.
The first is that for whatever reason they have never masturbated. Masturbation is often a woman's first orgasm experience.
The second is that they simply are not receiving the proper type of genital stimulation. Clitoral stimulation is needed by most women to have an orgasm. Without that stimulation, it most likely isn't going to happen.
There are some women who have psychological blocks when it comes to experiencing sexual pleasure. This may be the result of any number of past events in their lives, but even that does not mean they are physically incapable of having an orgasm. If they worked through those problems, they would be able to engage in orgasm-producing intercourse just like any other woman.
