I submit when it comes to masturbating, my methods or lack thereof, stem from an innate desire to keep things as simple as possible. I use no lotion. I seem to be partial towards my left hand. Though that may arise from the fact that i am right handed and need to be in precise control of the mouse cursor should anyone unwittingly decide to traumatize themselves(also the reason i use a blanket if anyone’s home). I’ve been using this combo for so long, it’s now become automatic.
As for perday frequency, it is in line with the law of diminishing marginal utility.
