Why isn't there a porn industry specifically for side-gays and/or bisexuals?

I miss that, because on all the gay porn sites you have to go searching—there’s no category for "sides." It really pisses me off. I want to watch a video where two adult men kiss tenderly, caress each other, engage in oral sex, masturbate each other, and so on. But in the end, it almost always turns into anal sex scenes. It’s really sad.
