I dynamically water pump in 60 min sessions. Most of the time it is pleasurable and I enjoy it. However towards the end of each session soreness creeps in - a sort of stretching soreness more obvious near the base not unlike from extending.
My main reasons for pumping are to grow and maintain and improve EQ. Certainly got girthier and now have to take more time to get the wife ready. Otherwise I have difficulty getting in. She definitely enjoys the extra size but I better be careful not to gain too much more girth. I was thinking of getting a bigger cylinder as I quickly pack the current one. Will now stick with it and see if I can get some more length gains with it.
Will continue to use the silicone pumping sleeve to keep fluid at bay. Fluid caused pumpiness makes sex difficult and less enjoyable. The wife certainly notices it.
