I have never been a sexually timid woman. Over a period of more than three decades I have explored sex play with my partner. We have engaged in intercourse (vaginal and anal), mutual oral sex, mutual masturbation and vaginal fisting. I never once responded to most of these activities. The only ones that caused a peak of sensation for me on occasion were anal sex and vaginal fisting, which did not compare with the sexual release that I obtain from using erotic fantasies when masturbating alone.
