# There is enormous variability in the sexual repertoires of U.S. adults, with more than 40 combinations of sexual activity described at adults’ most recent sexual event.
# Many older adults continue to have active pleasurable sex lives, reporting a range of different behaviors and partner types, however adults over the age of 40 have the lowest rates of condom use. Although these individuals may not be as concerned about pregnancy, this suggests the need to enhance education efforts for older individuals regarding STI risks and prevention.
# About 85% of men report that their partner had an orgasm at the most recent sexual event; this compares to the 64% of women who report 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.)
