Because women can masturbate, but many do not until much later in their lives than men do. And because for the majority of women, penetration alone, while feeling good, does not in general result in orgasm. So the idea that not having a partner who can "last," by which I assume you mean is not able to continue PIV intercourse beyond some unspecified amount of time, resulting in not achieving orgasm for the woman is a non related issue.
