This piece explains the difference between “highly sexual” women and women who aren’t quite so sexual. It appears there’s not really all that much that’s different:
… both highly sexual and less sexual women reported having sex for the first time at age 17, on average. And both groups reported having sex the same number of times per week (once/twice to three to five times). They also reported having had a similar number of committed partners (3.62 among highly sexual women compared to 2.56 among their counterparts). Highly sexual women did, however, report having had a greater number of casual sex partners compared to their less sexually interested sisters—on average, 7.96 versus 4.28, respectively.
