Sex

Sex is intercourse. There are several styles, most popular being anal (Something, often a penis, going in the ass), oral (Something, usually a penis or vagina, going in the mouth), and vaginal (Something, often a penis or dildo, going into the vagina).

You can do it with two people, three people (Thus called a threesome), four people (foursome), five people (fivesome), or 6 or more (Orgy). Doing it by yourself, though, is called masturbation, and generally isn't counted as sex.

When having sex, it's a good idea to wear a condom or some other kind of protection, even if you don't think there is any way for you or one of your partners to get pregnant. 1, protection can reduce the risk of getting an STD (Sexually Transmitted Disease.) And, 2, my mom was told that she was infertile, and they are pregnant with their 8th biological child now.

Jake: Me and Oliver had great sex last night!

Jane: You remembered to use protection, right?

Jake: Yeah, of course!

(Sorry if anything is incorrect. I'm a virgin asexual person, so I don't have much experience with the topic T_T)
