Every man should be doing kegel exercises every day to learn how to control your cum during sex. This will drive your woman crazy and she will be begging for more, asking if she's not pretty enough, wondering if their pussy stinks, start crying, asking herself if she should let you try anal, offer to invite her friend over for a three-way, etc.

Take from them what they always took for granted. The precious cum. It was always about the cum.
