You just need to pleasure Gin a few times before he gives up and starts his "training." He will eventually find out you're messing with him and runs away. I forget what you do to trigger his second event.
As for the public update, don't quote me on this, but I noticed it's about 15 days after the Patreon release. I guess the indivi is taking that time to fix bugs reported and polish the game before public release.
