Clamped bulb presses
Here’s a clamping variation to try out. It might also partially explain base girth gains from clamping. Haven’t seen it mentioned elsewhere.
While clamped up, and hard above the clamps, take a feel down below the clamps, in the BTB and perineum area. I find the this part of the shaft is nearly as hard as the clamped portion, and that it swells and forms a “bulb” that I then press on to increase the pressure. When I kegel and press, it increases it even more.
I like to do a kegel bulb press with one hand, and then use the other hand to squeeze the upper shaft and glans, increasing the pressure everywhere. With enough clamps it can be a very intense workout.
