How Vaginas Work
sexual intercourse | Description & Facts | Britannica
When it comes to men and sex , they're pretty easy to figure out. Men's penises become erect when they're sexually aroused, and they release ejaculate when they've had an orgasm. Because women's arousal is harder to detect, and because women's orgasms aren't essential to reproduction, many people -- both men and women -- assumed that sex was something women put up with to have babies, not something that could be enjoyed. Now, of course, there are plenty of resources, from Cosmopolitan magazine to sex therapists, who are ready to explain how a woman can gain pleasure from sex. For one thing, female arousal is now better understood. When a woman becomes sexually aroused, the labia minora become swollen and puffy, which causes salt water to push through the vaginal walls and provide lubrication. In addition, the Bartholin's glands at the vagina's entrance produce lubrication, but in both cases, that moisture is only provided for a few minutes, so additional lubrication may be needed to maintain comfort during sex.

The science of sex: what happens to our bodies when we're aroused?
Great sex goes beyond titillating tricks and quivering orgasms. Ian Kerner. Sex affects your brain in the same way drugs do. This is one of the chemicals that give you that exuberant feeling.
According to Don and Debra MacLeod's Lube Jobs: A Woman's Guide to Great Maintenance Sex , maintaining the sexual spark is akin to the way we maintain a car: we don't get to do the big check-up, so we do small upkeep to keep the engines running. The car maintenance metaphor is not very inspiring. It lacks poetry. What people want when they complain about the listlessness of their sex lives is to recapture the poetics of sex, the connection, the renewal, the playfulness, the feeling of aliveness, a sense of lifting themselves from the mundane -- not maintenance. All quick fixes, instructions, are intended to save us from our hectic lives.
