What's sex? At a glance:People define "sex" in different ways. It can include vaginal, oral, and anal sex, and other activities.Vaginal, oral, and anal sex have more risks (like pregnancy or spreading STDs) than other sexual activities.If you're going to have any kind of sex, it's important to make sure you (and your partner) both feel ready and are protecting yourselves against pregnancy and STDs.- See more at: https://www.plannedparenthood.org/teens/sex/whats-sex#sthash.309gaKmu.dpuf
