I find it weird you included sex in the OP...

IMO, sex does have something to do with it, something to do with the polarity of your body/blood...I can only go on my personal experiences but I flip the magnetic locks of doors all the time...

And like most rh neg folks I will kill a brand new watch battery in less than 1 week...blow all light bulbs if I touch them...especially the blue or purple or black lights...those I can't even take out of the package or they will be blown before they even go in the lamp...
