I know some women would disagree with me, but I think women who get little or no satisfaction from sex need to get more in touch with their bodies, primarily through masturbation. Sometimes we get so caught up in other things while with a partner that we fail to concentrate on the sensations we're experiencing. In my case, I was convinced that I was one of those women who would never have the big O and I was so busy doing a convincing job of faking it that I never really got to enjoy it. I was thinking about everything except the act itself: Does my breath stink from the garlic I ate earlier? Oh, god, I need to pee! Does my butt look big? I wish he'd turn off the light... Any number of things can ruin the experience for you. I found masturbating with my eyes closed and concentrating only on the sensations I was feeling enhanced my sex life. Not only that, but being more open to trying different positions made vaginal orgasms possible for the first time in my life!
This does not work for everyone but in my case, I needed to learn what I liked and felt comfortable with before I could communicate this to my partner and get my needs met.
