He just stopped. He never did that much sexual content anyway. He'd stream for many hours and only jerk off for a few minutes, right before going to sleep. It never felt like he was too much into that aspect. And then, he got a lot more careful after he found one of his streams get leaked so he stopped showing his face while he'd be doing anything sexual. During his last streams, I think he didn't even get sexual. And then, he just stopped the streams altogether. Maybe he just wasn't enjoying it anymore.
