Phallus animation after climax bugs out and visually stays "Fully-aroused" until next arousal level is achieved. Save and load also returns phallus picture to correct "Flaccid" state.
On a picture i have grapple.win situation and phallus is visibly full mast, but i can't penetrate because this is just bugged out phallus image.
Bug stays between fights, so if im not gonna achieve next arousal level, then visually phallus stays up until i save/load the game (or get aroused enough).
