As a top, I voted the fuck. But as a former bottom, I fully understand those who voted for the load.
I'm multiorgasmic, and I liken my orgasms to going out to dinner - the first is like the appetizer in that it usually arrives quickly, the second is like the main course in that it takes longer to arrive and the third is like dessert in that sometimes you get it and sometimes you don't. Plus, the longer I fuck until I cum, the larger the load gets, (Think of whipping cream.)
Plus, with 25mg of a little blue pill in me, I can pretty much get hard at will for ~18 hours and fuck long after I can no longer cum.
