Discussion Not all sexual behavior involves a partner. Two ways that people sexually stimulate themselves include masturbation and sexual fantasy. Both women and men masturbate, although men masturbate more regularly. Men usually masturbate by stimulating the penis in an up and down motion with a hand circled around the penis. Masturbation can enhance partnered sex by increasing sexual variety and by increasing one's own familiarity with the types of movements that are sexually arousing.
Many people sexually fantasize about interacting with a sexual partner during masturbation.
Common fantasies include kissing, sensual touching, oral-genital stimulation, and seduction. People also commonly engage in sexual fantasies during partnered sex, and such fantasies can enhance sexual arousal. Vaginal intercourse can be performed in many different positions. The woman on top position allows for the man or woman to stimulate her clitoris manually during intercourse for increased sexual excitement. Common positions for vaginal intercourse differ for various couples.
