Taking the pill doesn’t just prevent pregnancy—hormonal birth control can also clear up a woman’s skin, make periods less painful, and affect mood. And now, a new study says the type of birth control a woman uses can impact how often a couple has sex.
Women who felt the most committed to their relationships had the most sex when they were on birth control with higher levels of progestin and lower levels of a form of estrogen called estradiol. On the other hand, women who felt less loyal to their partners had the most sex when they took birth control with lower levels of progestin and higher levels of estrogen.
The hormonal differences only influenced frequency of intercourse—and not oral sex, masturbation, or sexual fantasies.
