Sex is a bodily function with the purpose of perpetuating the survival of the species (or discontinuing, if you're a homosexual), which is why it feels good (except if you happen to have been circumraped). In its superficial form, sex is an act of pleasure and love and can occur in a variety of modus operandi including IRLintercourse, Internets sex, and phone sex (from fapping to "dirty talk" with a loved one to inserting an iPhone set to "vibrate" into the anus or vagina and calling it repeatedly on redial). Things such as chemistry, beer, chloroform and sex toys can be used to enhance the sexual experience for the parties involved.
