If a woman can't reach orgasm, is it the man's fault or the woman's fault? because it seems like the man is always blamed.

Female Anatomy: Many couples, in fact, probably the majority of couples, find that intercourse alone does not stimulate the clitoris enough to reach orgasm. It is the female's responsibility to be in charge of her own orgasm. But, if you love this woman, it is your opportunity to include clitoral stimulation during intercourse. I often recommend to my patients that they get a guidebook: "the joy of sex".
