Hence the word pre-orgasmic began to be used. Yes, many women under 20 are pre-orgasmic, since they haven't learned to orgasm yet. However, many women do learn, through masturbation, to orgasm in childhood. Alice recently heard about a child of 5 who masturbated and had orgasms. There is no value judgment here, just information.
Some women have their first orgasm with a vibrator on or near their clitoris.
Other women have their first orgasm with the stream of water from pulsating shower heads when they are bathing. Orgasm is an interesting thing. Women can read about it and still not make an connection. Alice knows about a woman who said she wasn't having orgasm, but when she learned more, her body was, in fact responding with orgasm, and she had no idea that THAT was the sensation she was still seeking. Sexual pleasure for women is not tied to reproduction and getting pregnant.
