Having sex for the first time can be a little nerve-racking, no matter who you are or who you want to have sex with. For example, they could identify as bisexual , pansexual, queer, or even heterosexual. It also includes other people who have vaginas, people with penises, and people with intersex genitalia. Heterosexual couples, for example, may have oral, manual, or penetrative sex. It all depends on the couple and what they like to do. Through school, the media, and our communities, most of us learn that sex is about a penis entering a vagina.
