Often men believe women are the same, and once they figure what works for one woman they apply that same method to all the other women they are intimate with, and that's one of the major problems.

5% of women have true multiple orgasms only through intercourse and these women typically find oral sex uncomfortable.

One of the biggest impediments for women is that they have never really understood, looked at or examined their own genitals. They have not really figured out what kind of stimulation and where feels best for them, so they are not able to guide a partner in this.
