It won’t do anything to you. Trust me.
If you engage in that kinda heating during your sessions, you should be fine. I never had any problems, never got my nuts fried and I still shoot like a racehorse, and piss, too, but all I can say is check it out and if you feel like it’s not for you, stop using it.
I had good and great success with it. Just don’t put the lamp too close to your dick.
