RoseTracker| Researchers at Penn State followed 434 students, traditional freshman age 17 to 19 for the course of their college careers, surveying them four times on the subject of their relationships with others and their levels of satisfaction with their own appearance.
The most significant finding was that college-age males generally became more satisfied with their appearance after their first sexual intercourse, whereas college-age females became slightly less satisfied with their physical body image.
Generally the women became more positive with their physical appearance from freshman to senior year of college, while men became less satisfied.
About 1 and 4 young adults reported engaging in sexual intercourse for the first time. After this event, the women’s satisfaction with their appearance decreased, with the opposite result among the men. via Science Daily
