Five year update:
@Slippery... nice work. This is a five year update and I never collected a baseline value. Judging from the spot on my towel I guess the volume hasn't changed much (still in the middle of the curve approximating 1/4 teaspoon.) Of Aneros tools, MGX remains the tool that produces the "mostness" The big change with age has been the viscosity of my precum. It's rather stringy now. ... rook
I produce it in a continuous stream most times, especially when using an MXG. Love the stuff! Great nipple lube.
I’m 61 and the use of my Progasm combined with nipple play produces a good quantity of precum; a lot more than when regular masterbation.
