Gay porn star Austin Wolf is facing some stiff restrictions after he serves his prison sentence for child sexual exploitation ... and one of his limitations is a real kick in the balls! Wolf won't be allowed to watch any adult smut films and, of course, kiddie porn after completing his 19-year term behind bars, according to new court docs. He's also required to undergo a sex offense-specific evaluation and mental health treatment with polygraph tests tossed in to keep him in check. As for his chosen profession, Wolf will have to refrain from viewing or possessing adult porn unless his treatment provider signs off. What's more, Wolf is barred from contacting the victims in his case and he can't have any contact with anyone under 18.
