Not all…but the majority (98%) are lol. Nino Valens is gay, which is one of the few times that a model is advertised as gay and hey! he actually is gay and not just putting on an act for viewers (like Dolph Lambert), Rafael Moretti is gay and has a boyfriend & Garrett Dornan is gay and has a boyfriend, but neither film anymore and have 1-3 scenes each (wonder if being gay had something to do with it). Milan Sharpe is gay and had an Asian exchange student boyfriend last I checked, Jean-Luc Bisset is bi/gay, Christian Lundgren claims to be bi and shows interest in men. Those are the only ones I know about.
Kevin Warhol & Jack Harrer claim to be bi, but have never dated men to my knowledge and Kevin has a long time girlfriend that is super friendly with BA models and employees. Jason Bacall has a girlfriend, Adam Archuleta is so straight, it hurts, Andrei Karenin strips for women and only follows women on IG, Jon Kael is very straight (look at his Twitter likes), Hoyt Kogan is 100% straight off camera, Joaquin Arrenas has a girlfriend, and I don’t know about Jerome Exupery, but I’m assuming that he’s straight (Helmut Huxley is straight, too, and has a girlfriend). Some of them can’t even maintain the gay act on Twitter and like/follow women/porn stars/cam models on their gay porn accounts (Kevin, Jack, Hoyt, Jon, Kieran Benning, Jamie Durrell, and others do this, Christian is the only one who likes and follows male accounts and pictures).
