Though sexual intercourse generally involves penetration of the body of one person by another, sex positions commonly involve penetrative or non-penetrative sexual activities.Three categories of sexual intercourse are commonly practiced: vaginal intercourse (involving vaginal penetration), anal penetration, and oral sex (especially mouth-on-genital stimulation).For example, the spoons position is recommended when either partner has back problems; the starfish position is recommended to achieve orgasms more easily and the missionary position may be uncomfortable for the receiving partner if the weight of the inserting partner, relative to the receiving partner's, is a problem.
Pregnancy is a potential result of any form of sexual activity where sperm comes in contact with the vagina; this is typically during vaginal sex, but pregnancy can result from anal sex, digital sex (fingering), oral sex, or by another body part, if sperm is transferred from one area to the vagina between a fertile female and a fertile male.Some people are limited by physical disabilities in the sex positions which they may use without pain or other discomfort.Other physical limitations of one or both participants also limit the sex positions which they may adopt.Sex acts may also involve other forms of genital stimulation, such as solo or mutual masturbation, which may involve rubbing or penetration by the use of fingers or hands or by a device (sex toy), such as a dildo or vibrator. There are numerous sex positions that participants may adopt in any of these types of sexual intercourse or acts; some authors have argued that the number of sex positions is essentially limitless.
Sex manuals usually present a guide to sex positions. In the Graeco-Roman era, a sex manual was written by Philaenis of Samos, possibly a hetaira (courtesan) of the Hellenistic period (3rd–1st century BC).
