| Abstract: | Seasonality among animals has an important function in breeding cycles. Research focusing on conception and coital activity in humans has called attention to the possible existence of circannual rhythms in human sexual activity. We studied the diurnal variations, seasonality and subjective sexual preference among young women in Israel-focusing on their first intercourse. The survey included 135 college students who completed a self-report questionnaire. Half of the subjects (50%) reported loss of virginity during the summer with an almost equal distribution among the other seasons. Over 85% of the subjects had their first intercourse either in the evening or at night. Subjective sexual – seasonal – preference was reported by 44.4% of the subjects but no correlation was found between the preferred season and actual loss of virginity; except for the autumn “preferers”. Our study supports previous research generalizing the sociological explanation for seasonality of the first intercourse. |
