Real Sex is a documentary television series broadcast on and a production of HBO. As its name implies, Real Sex is a sexually explicit "magazine" which "explores sex '90s style."

Real Sex explores human sexuality, from the latest sexual fads to casual sex festivals and home production of pornographic movies. The show typically explores three to four topics each episode. Segments are separated by street interviews with random people, relating to the episode's topics.

Episodes of the show investigate RealDolls, "Swingstock," a cunnilingus seminar, a perpetual sex machine for women, and lovemaking in chocolate.

The last Real Sex episode aired in 2009. Older episodes as well as "best-of" episodes are frequently re-aired during late nights on HBO.

It spawned a spin-off series called Pornucopia.
