According to Meston et al., (2004), an orgasm is a fleeting, erratic, very pleasurable feeling that occurs in females and causes a shift in consciousness. Wallen and Lloyd (2011) suggest that there are variations among women in achieving orgasm. They note that some women can reach orgasm solely through sexual intercourse, while others need simultaneous stimulation of the external parts of the clitoris to orgasm during intercourse. they added that, no matter the conditions, some women may also never have an orgasmic moment during a sexual act.

For this reason, it is not always true that a woman may have an orgasm only by having a man ejaculating into a vagina or any other part of a person's body.

I am asking women to explain how they orgasm with a lover. Over the many years of my research I have found very few women willing to comment. Certainly no woman can orgasm through intercourse, which is determined by male responses. No one can orgasm within time limits set by another person. My experience is that there is no arousal with a lover. This explains why no one can name any female erotic turn-ons with a partner. I have found that orgasm occurs through masturbation because I need privacy to use the erotic fantasies that cause my mental arousal. Few women seem to understand that arousal and orgasm are responses of the brain to eroticism.
