Written stories about people doing it, often known by the classier and more evocative term, Erotica.
According to that other wiki, Erotica has been around since the time of The Bible. This just means that even way back when, people still wanted to read about other people doing it.
Although it's like porn, Erotica can be educational, well-written, and sometimes even pass into the literary canon as acknowledged classics. This ranges from the ancient and quasi-sacred, like Kama Sutra — full of information about sexual relations, with a brief foray into cryptography and other methods of concealing your salacious affairs — to the fairly modern, such as Lady Chatterley's Lover. In some cases an erotic book can come to challenge entire philosophies about sex and sexuality, like Venus in Furs. As mentioned above, even the Bible has erotica in it: the "Song of Solomon" a.k.a. "Song of Songs" is remarkably couched in sensual language. One of its opening passages, "Let him kiss me with the kisses of his mouth" is one of the most famous verses of the Bible itself. Since sex is such a key part of most people's experiences of being human, erotica, in the hands of a skilled author, can easily cross over into Lit Fic.
Modern day books tend to deal with the emotional side of sex and sexuality, and often — with varying degrees of success — attempting to introduce a story or arching plotline. Some of these have been adapted to film.
