I think it depends how much cum the Cum High character ingested or is cumflated with--the threshold is at 3000 mL or higher. That shoudl cause the Cum High effect. If the effect wears off, there is a cool down period of about 2 days until the character can get high again.
The "Cum High" status effect should now be able to track the total mLs of cum ingested and level up based on that. The stat debuff values are now tracked with one value instead of three since they are all the same value, essentially. The thresholds are still the same (higher each stage), but at least the progression of the effect will feel more consistent. The effect's tooltip will show the current tracking for clarity.
After the update, if your character already has the status effect, it may act a little weird with the numbers, but after it is regained again, it should function as expected.
