title: Increased sexual activity during the midcycle portion of the human menstrual cycle.
abstract: Daily sexual activity of sexually active lesbian couples was recorded over a 14-week period. Significant peaks in sexual encounters and orgasms were found during the midcycle portion of the menstrual cycle. These results demonstrate a pattern of increased midcycle sexual activity independent of interactions with males, type of contraceptive method, or fear of pregnancy.
