Will Too much Natural Juice spoiling the fun?

It's so nice when the mm is very much aroused and lots of natural juice flowing, but when it becomes like the floodgate is opened and the kitty become so slippery that my old jj will not feel a thing, is like when the kimchis put like half a bottle of ky.......... what do you think? Also want to emphasize my jj size is average and not superbig or supermini
