This game shows promise, but I think it makes the same mistake a lot of games like this make: the majority of the game's sex scenes lead to a game over. This means that a player is punished for finding the sex scenes in a porn game, a type of game that people mostly play specifically for those scenes.
An easy solution to this would be to implement a difficulty setting in the options menu that just makes it so that when you lose a fight, the game continues on as though you had won it, xp and everything. Call it Casual Mode (or Submissive Mode, if we're going with the theme of this being a porn game). Maybe also add another difficulty setting that makes it so a game over gives you the option to begin the fight from the beginning, since some players will want to submit to an enemy just to see what the game over for losing to that enemy is like and this just lets them see that without forcing them to reload their last save and get back to that enemy.
This being optional means that anyone who for some reason wants their porn to actively discourage them from seeing anyone have sex can still have that if they want.
Besides that, I think this game looks pretty good. Particularly the grapple and undressing system, which is an interesting way to incorporate sex into the combat mechanics.
