I'm using a laptop on a bed in my hotel room (so can't use my normal wired setup). I noticeably feel something wrong with my balls doing this. It isn't pain, I just notice something there. Of course it is damage as literature has confirmed this with studies on sperm health.

It isn't psychosomatic, often I'm not even thinking about it till I feel the sensation, and I'm like "oh yeah wifi damages sperm". Then when I turn it off it stops.
