hello, i was just looking at this and im interested in it. I like to lift weights, so im wondering if i should take it off while lifting or leave it on. I notice that sometimes when i lift, my penis and balls hang reall low and loose, but sometimes they retract a bit. I wear boxers so i would hate to have it fall off while lifting.
also, i was thinking of making one myself(i remember back in chemistry we made batteries and that is all this is), but im wondering how much the materials would cost(the ones they used in that website you gave).
Also, i was thinking of maybe adjusting the different metals for a different voltage, so im also wondering if there is a max voltage(where it may cause damage after this point) or a min voltage(i would aim to at least get .5 but i wouldnt want to get too low and have it not do anything)
thank you for the help.
