Mark is using YouTube to build a revenue stream. He can't afford to take too much risk because he'll get banned. So, of course the content is boring for those of us who want to see more. Until he changes venues, I would expect more of the same.
On the other hand, there are creative ways to tease, and keep the tease exciting. Perhaps he's out of ideas and needs inspiration help from his audience. I for one told him to get rid of the shorts and start using a white towel. He listens to his fans. The white towel videos reveal great swelling, bouncing cock. It's easy to imagine licking it and going down on it.
