Yeah, you're right, we have to wait and see! But considering this is a full feature movie about the affairs of a woman, and there are only 3 guys in it, chances are high that Drew is involved with at least one of the women!
Besides, I have always thought that Bruce LaBruce has a huge fetish for gay men sleeping with women. There are so many scenes and movies where he brings women in. (And I'm not talking about his bi work only, I'm talking about his GAY work, too!) The gay porn movies he directed for Cazzo were the first I ever saw of him. In nearly all of them a woman gets fucked by an openly gay man. For example, former Austrian actor Max Schneider lost his goldstar in one of them. And LaBruce himself has talked about a fight he had on the set of "Skin Gang". He was angry because he wanted gay guy Slava Mogutin to fuck a woman for real in this movie, but Cazzo only allowed a faked scene without penetration... So yes, I'm sure LaBruce would love to film another gay man losing his virginity to a woman! But it's Drew's decision of course. We'll see.
