I’ve been wondering about this as well.. I just got my pump last Tuesday and so far I’ve really enjoyed the experience and feel like it’s working my dick in ways that manual exercises have failed to accomplish for me. However, I’ve made a few observations and I’m wondering if they indicate anything in particular or if they’re normal.
When I got into the pump fully erect, even while on some generic Viagra, if the pressure drops at all or if I just let the pressure out completely, my erection goes away instantly. The reason I found this weird is because I thought pumps were supposed to give guys erections who couldn’t otherwise achieve them. Am I mistaken? Is this even an issue?
I have been getting night/morning wood and a lot of stretching in my skin, which didn’t really happen on a regular basis with 3 months of manual exercises. So that’s a bonus. Also more frequent random erections.
Anyways, thanks for any feedback. This pumping stuff seems to be just what my dick needs to grow.. Besides the scary sight of my veins bulging in the tube and looking like they’re about to burst I am totally enjoying it lol :-p
