gay: HOMOSEXUAL. Refers to both homosexual men and homosexual women (also called LESBIANS).
teen: Sex performer that either is or appear to be nineteen or under.
hardcore: Explicit movies or videos that show genitals, especially an erect penis, and often include penetration. In this meaning, "hardcore" is the exact opposite of SOFTCORE. But for many porn videos, it just means an intense or dangerous sexual activity.
