Unused Resource YT Channel 1.1M Views!

I'm a complete IM noob. I share a YouTube channel with a friend. It has 5 videos that are all adult restricted with 1.1M views total. We have almost 2k subs. We don't really intend to make any more videos for the time-being so suggestions for monetizing would be much appreciated. I half-hardheartedly put a clickbank link in the description of one of the videos but it was rejected by YT.
