Porn vs gay porn

My SO and I have recently got a job offer to do porn, and because money is really tight and I don't see anything wrong with it and he doesn't either, we both agreed to it. The only problem is that they adviced that he start with gay porn as a starting point and because it offers a lot more money. My SO said as long as he isn't receiving anal but only the other guy give him oral he was going to do it as long as I said I was comfortable with him doing it. I'm kind of hesitant just because I thought it was just me and him and now he wants to venture off on his own.... And on ontop of that its a guy giving him oral. Any advice?
