Sexual intercourse or coitus is the human form of copulation. In a wider context, the term sexual intercourse may refer to a wider range of sexual activities than the term coitus, which usually only refers to vaginal intercourse. See human sexual behavior for a discussion of the broader sense of sexual intercourse.

Sexual intercourse may be preceded by foreplay which leads to sexual arousal of the partners, resulting in erection of the penis and natural lubrication of the vagina. The erect penis is inserted into the vagina and one or both of the partners move back and forth to stimulate themselves and each other usually to the point of ejaculation and orgasm. A detailed description of the physiology of sexual arousal and orgasm can be found in the article Human sexual response cycle.

Wank your way to nasal clarity
A paper in the Journal of Medical Hypotheses, "Ejaculation as a potential treatment of nasal congestion in mature males" (Zarrintan, S) proposes a good hard wank to relieve nasal congestion in men: So the author proposes a more...natural method of decongestion. "It is known that sexual arousal in men is followed by penile erection and subsequent ejaculation" (unless of course you've taken too much Viagra or something). The emission phase of ejaculation is under the control of the sympathetic nervous system, which of course has lots of adrenergic receptors. The author reasons that ejaculation will stimulation adrenergic receptors in the refractory period immediately afterward, and stimulation of your adrenergic receptors will give you relief from your cold. The author proposes that, with proper scheduling of masturbation and/or sexual intercourse a guy could keep his nose clear for the rest of his life! I wonder how the partner takes that. "Honey, come here, my nose is stuffed up..." And what if your nose is REALLY messed up? I hope those people work from home. And if a guy can keep his nose clear for life, what about us ladeez? My allergies bother me, too, you know. I think this needs to be tested, both on men and women. So I want to hear back from all of your whether it worked. Wait 'til the hay fever sets in, go at it like rabbits, and then leave a comment with whether or not it worked. Obviously this is not a well controlled study, but I don't know that I want to ask whether it was masturbation or intercourse, and I wouldn't trust anyone with a timer in the few minutes after sex to measure their refractory period. So this is more of a pilot than a real test. Go to it! This is your homework for the weekend! Screw the sudafed: When your nose ain't great, masturbate!...
