I don't know what your plans are with the sexual part of the game for me, it's not why I play the game, to be honest. I really enjoy the hack slash part of it, the game loop is really fun at the moment even tho there's not much to do when you reach 20 that's it… Still it's fun.
But if you really wanted to do something about the animation part you could just add an Orgasm Bottom so you can either leave the animation to go for as long as you want or just orgasm instantly or a few secs after the animation started IDK… I'm not a game dev nor know anything about coding, hah.
As long as I can progress through the game with as little sexual acts as possible, I'm going to be happy.
