New York City students and their sex lives

In an article titled “N.Y. City students surveyed on sex lives”, Karen Matthews addresses the sex lives of adolescents in New York City. One tenth of these high school students report that they have had at least one same-sex partner, and teens who have had contact with both sexes report higher rates of dating violence, forced sex and risky sexual behaviors.According to Dr. Susan Blank, the assistant commissioner of the New York City Department of Health and Mental Hygiene, students having both male and female partners experience a lot of adverse health problems.Among New York City high schools, surveys were administered, 7,261 students claimed they had had sexual intercourse. Among the sexually active males 93.1% had contact with only females, 3.2% had contact with males and 3.7% had both male and female partners. When looking at the sexually active females 88.1% stated they only had sex with males, 3.2% had only female partners, and 8.7% had both.While there are no comparable national numbers, other states have reported lower numbers of teens who have had sex with same or both sexes. This leads us to wonder why New York City has higher rates than the rest of the U.S.. What do you think some of the reasons could be?
