I heard the term the first time about 2 weeks ago. I do not know how to set up a poll to see what percentage partake in this but am courious, for myself it is a no. Far from prude but why? Never had the urge to see what my cum tasted like. What if you get hooked and end up swallowing your cum after you masturbate and then that is not enough anymore and it leads to GS & BS ( Ok, the last sentence is for humor ). Again to each his own but that thought never ever occured to me.
