While jerking off, when you start to cum, do you pump your hand over your whole cock, shaft and head, or just work the shaft when you cum. So I have noticed when I jerk off I pump my hand over the head and the shaft of my cock, but when I start to cum I only "work the shaft" and not the head of my cock. I have also noticed that when my wife jerks me off, she runs her hand over both the shaft and head while I cum. Now this is sometimes almost a painful feeling to have her pumping my whole cock while the sperm is spurting. Since this somewhat minor revelation I have noticed that a lot of porno men also don't stroke the head when they cum. Now is this because it is more comfortable to cum while just working the shaft? seems to be for me. or is it because you can see the cum fly better?
