having had an orgasm at their most recent sexual event. (A difference that is too large to be accounted for by some of the men having had male partners at their most recent event.) ( NSSHB, 2010 .) Men are more likely to orgasm when sex includes vaginal intercourse; women are more likely to orgasm when they engage in a variety of sex acts and when oral sex or vaginal intercourse is included. ( NSSHB, 2010 .) Among ages 18-59, older age for men is associated with lower likelihood of his own orgasm; for women it is associated with a higher likelihood of her own orgasm. Age is not associated with the partner's orgasm for either men or women. NSSHB, 2010 . Women are much more likely to be nearly always or always orgasmic when alone than with a partner. However, among women currently in a partnered relationship, 62% say they are very satisfied with the frequency/consistency of orgasm ( Davis, Blank, Hung-Yu, & Bonillas, 1996 ). Pregnancy Roughly six million U.S. women become pregnant per year. About two-thirds of these pregnancies result in live births and roughly 25% in abortions; the remainder end in miscarriage. ( AGI, 2005 ). The U.S. teen pregnancy rate fell by 27 percent between 1990 and 2000, from 116.3 pregnancies per 1,000 girls aged 15-19 to 84.5. This data includes live births, abortions, and fetal losses. Pregnancy data includes live births, induced abortions, and fetal losses ( NCHS, 2004 ). Prostitution/Sex Work 15.3% of
