Softcore pornography is a form of filmic or photographic pornography or erotica that is less sexually explicit than hardcore pornography. Softcore pornography depicts nude and semi-nude performers engaging in casual social nudity or non-graphic representations of sexual intercourse or masturbation. Softcore porn precludes explicit depictions of vaginal or anal penetration, cunnilingus, fellatio and ejaculation. Visual representations of genitalia (full nudity) are typically permissible in a softcore context in printed media, and increasingly so in film and television. Erections of the penis may not be allowed (see Mull of Kintyre Test), although attitudes towards this are changing.
Portions of images which are considered too explicit may be obscured (censored) through various means. These techniques include the use of draped hair or clothing, carefully positioned hands or other body parts, carefully positioned foreground elements in the scene (often plants or drapery), and carefully chosen camera angles.
In most cases the sexual acts depicted in softcore pornography are entirely simulated by the actors and actress; no actual penetration occurs. Often the actors wear latex genital covers to prevent physical contact. Film directors go to great lengths to obscure such covers on screen, but often fail to completely hide them. The comedian Pablo Francisco joked about this "facade" during one of his routines: "The reason they call it soft porn [is] 'cause it doesn't get you hard."
Hardcore film makers will sometimes make edited softcore versions of their films for the hotel pay-per-view market, cutting in less explicit angles of the sex scenes.
