Thanks Antonio for commenting. You need to understand that women are not aroused with a lover. They provide a man with regular intercourse foremost to establish an emotional bond that keeps a man tied into a supportive relationship with them. Once again my research relates to SEXUAL RESPONSE. So I am looking for people to relate my questions to understanding how women (and men) achieve arousal and orgasm. No one can name even one female erotic turn-on with a lover. Responsive women use surreal erotic fantasy to masturbate to orgasm by identifying with the penetrating male. The penetrating male enjoys the erotic pleasure of sex and so it is only he, not even a male receiver, who pays for sex - directly or indirectly. Women need compensations for providing male sexual pleasure.
