How do you shave your balls? Every time I've tried with my trimmer it pinches and tears my sack and I'm too traumatized to try it again unless there's a full proof bloodless method. Usually I just pluck as many as I can tolerate while I'm sitting around watching YouTube or somethin. But it's such a pain (literally). Pic unrelated
I second using the safe razor, albeit I would recommend using different ones for face and balls. The reason is that I assume that an ideal and universal razor may not exist, the ones I tried are usually either better suited for the body, or more comfortable to apply to the face, that is if we exclude those that are equally bad for everything.
Regarding the dulling of the blade, it may greatly depend on the brand and quality, so some experiments are required ¯\_(ツ)_/¯
