And I include in that the typical scenes of solo masturbation, "mainstream" coupled sex, group orgy, MSM/girl-girl/mixed bisexual/transgender/negotiated BDSM, and all the different subgenres and variants ("MILF", stepmom/stepdad, mature, interracial/"Ace of Spades"/BBC, BBW, etc.). I make no judgement on the particular personal preferences of consumers, performers, or adult providers; I consider porn to be just one of many artistic genres.
