Austin, the character, also has the advantage of being written as fully committing to the free love swinger movement of the 60s. It would not stretch credulity if his 90s era handlers were paranoid about Austin finding out his partner is a gay man, but Austin himself is completely nonplussed by the news. Hell, he could even allude to having same-sex experiences of his own ("You know, when you are at the bottom of an orgy pile, you don't always know where your bits and bobs are going, and you certainly don't care. Yeah, baby!")
