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.
There is already a mechanism in the game for people that are sitting close to the max storage. It is called Masturbate, -25 cum and -25 calories. Unless people are going for some type of meme, the gift from the Sedusa statue will actually recover calories, so as long as someone is not trying to stay close to the edge of max cum people should be fine.
Instead of a mechanic that turns the MC into a high pressure fire hose 'just because', leave the drip mechanic as it is and let the player manage their resources, such as cum stored, statue blessing, or available calories.
For anyone that is not aware of the skills: Open the Inventory and press left or right and it will shift to a skills page where there will be 2 skills, Rest +25 HP, -25 calories, and Masturbate -25 Cum, -25 calories.

Another alternative, using what is already in the game, would be to alter the summon tentacle skill. Instead of taking 10 HP per summon, it has a cool down timer that is shorter, but, akin to the summon book, that adds +2 or +3 cum drip and +2 or +3 calories for 10 turns or so, with a 10 turn cool down after the buff expires. That way your character would remove SOME stored cum at a much higher rate, but not at an over powered rate. Same thing for the calorie generation, it gives enough that you can use one of the skills to heal or remove even more stored cum.
