Oral sex is a broad term applied to both sexes. Specifically, the act of pleasuring the female genitals through mouth and tongue is known as cunnilingus, while the act of stimulating the penis is termed fellatio. The practice of oral sex is an almost inevitable part of intimacy and an important thing to discuss with your partner. It is as intimate as intercourse and can be source of great pleasure and intimacy for two consenting adults. The first thing to remember concerning oral sex is that each individual has their own preferences and some may even take a lot of convincing to try it. Whatever the case may be, it is important for both partners to communicate to each other what they do and don't like. Next issue to address is personal hygiene. This is one reason why oral sex with someone you've known for some time is still preferable to casual encounters with just anybody.
