Fifth, the definition of "sexually explicit conduct" (the visual depiction of which, engaged in by an actual minor, is covered by the Act's pandering and soliciting prohibition even when it is not obscene) is very similar to the definition of "sexual conduct" in the New York statute we upheld against an overbreadth challenge in Ferber. That defined "sexual conduct" as "`actual or simulated sexual intercourse, deviate sexual intercourse, sexual bestiality, masturbation, sado-masochistic abuse, or lewd exhibition of the genitals.'" 458 U.S., at 751, 102 S.Ct. 3348. Congress used essentially the same constitutionally approved definition in the present Act. If anything, the fact that the defined term here is "sexually explicit conduct," rather than (as in Ferber) merely "sexual conduct," renders the definition more immune from facial constitutional attack. "imulated sexual intercourse" (a phrase found in the Ferber definition as well) is even less susceptible here of application to the *1841 sorts of sex scenes found in R-rated movieswhich suggest that intercourse is taking place without explicitly depicting it, and without causing viewers to believe that the actors are actually engaging in intercourse. "Sexually explicit conduct" connotes actual depiction of the sex act rather than merely the suggestion that it is occurring. And "simulated" sexual intercourse is not sexual intercourse that is merely suggested, but rather sexual intercourse that is explicitly portrayed, even though (through camera tricks or otherwise) it may not actually have occurred. The portrayal must cause a reasonable viewer to believe that the actors actually engaged in that conduct on camera. Critically, unlike in Free Speech Coalition, § 2252A(a)(3)(B)(ii)'s requirement of a "visual depiction of an actual minor" makes clear that, although the sexual intercourse may be simulated, it must involve actual children (unless it is obscene). This change eliminates any possibility that virtual child pornography or sex between youthful-looking adult actors might be covered by the term "simulated sexual intercourse."
