True story... I was livin at my grandparents in BR for like 2 months bc I had some people in my condo and I was working in BR and boning gee faux. Well whenever I would fap in my grandparents guest bathroom, I would get this crushing headache right as I was going. It'd last for like 30 minutes. This was for like a 2-3 month period. I think I subconsciously felt bad for fappin with granny in the other room and that's how it manifested itself.
So there's a time when fapping wasn't pleasurable
