The magnitude of this association is most dramatic among the youngest females—for example, the odds of intercourse among 13-year-old females with a partner six years older are more than six times the odds among 13-year-old females with a same-age partner (odds ratio, 6.4), while 17-year-old females with partners six years older have about twice the odds of intercourse when compared with those who have a same-age partner (2.1).CONCLUSIONS: Young adolescent females with substantially older partners are much more likely than their peers to have sex with their partner, which exposes them to the risks of pregnancy and sexually transmitted diseases."True love can be ageless," declared actor Doug Hutchison, 51, an actor who starred in the television series "Lost," when he announced his May marriage to Courtney Alexis Stodden, a 16-year-old beauty pageant queen turned aspiring country star. Kelly's rumored romance with 15-year-old singer Aaliyah to rocker Ted Nugent falling for 17-year-old Pele Massa in 1978 -- and becoming her legal guardian because she was too young to marry him -- relationships between older men and younger girls never fail to make us squirm. states, a person can't legally consent to sex until age 17, and individuals under 18 years old must have a parent's permission to marry in all states except Nebraska, where the legal marriage age is 19. Lou Ann Brizendine, who has written about brain development in males and females, says that girls' brains are as much as two years ahead of boys' during puberty and that boys may not even catch up to girls until late adolescence or their early 20s, so a few year between partners can -- and often does -- make for a compatible match.
"If you meet him and decide he is wonderful, she should be allowed to date him," she says.Some 16 percent of girls had sex with male partners who were 4-6 years older and 11 percent had partners that were 7 or more years older.According to the NCHS's William Mosher, the average age for first-time sex for women is between 16 and 17.METHODS: Data from 1,975 female participants in the National Longitudinal Study of Adolescent Health were analyzed using logistic regression to determine whether the age difference between an adolescent female and her romantic partner is a risk factor for sexual intercourse.RESULTS: Adolescent females involved with an older partner have higher odds of having intercourse with that partner than females with partners their own age, after adjustment for demographic covariates.
