I wonder if the dev plans to add some sort of limit for cum (max 500 or whatever) and haven't done that yet just to let the players have fun for now. The only drawback currently is when you're near full and want/need to activate the ring effect or stun a mob but cant. Perhaps something like the more near the limit you go the faster it starts to drop due to the pressure being higher than what the character can hold, with a visible effect on the character, like dripping and leaving a trail when walking or something similar, as a passive alternative to the pumpkin/masturbation. To avoid that new objects/consumables could be added to the game, like seals and/or plugs, to prevent/delay the drop.
