There are other types of sex, though, so when people say "vaginal sex," they're talking specifically about the kind of sex where a man puts his penis into a woman's vagina. It's also the only type of sex that can result in a woman getting pregnant. Okay, So What are the Other Kinds of Sex? The word "sex" means anything that involves sexual activity or gives you sexual pleasure in any way. Here are some different kinds of sex, with links to more information about each of them: Oral SexAnal SexMasturbationMutual Masturbation Does Vaginal Sex Hurt?
