Females generally get more easily sexually aroused during ovulation which usually happens about 2 weeks after the first day of her last period. The reason for this is that a female can only get pregnant when she's ovulating. Since the biological purpose of sexual intercourse is to get the female pregnant, her body is going to hormonally encourage her to have sex while she is ovulating. Many women secretly yearn to sexually surrender to a powerful male, one who will take control and will absolve them from the responsibility of achieving an orgasm. Why do you think "bodice-ripping" romance novels are so popular among women? For these women, the thought giving up responsibility for their sexual satisfaction is a powerful turn-on.
