I was trying to start working out at the gym and to fight boredom I brought my tablet with me to watch an old show (Northern Exposure). I was on the elliptical watching an episode and up pops a sex scene, and I could see one guy maybe giving me a weird look, but I was uncomfortable watching it because if someone looked at the wrong time it may appear that I was watching porn, and could get me kicked out of the gym (for watching a 30 year old network TV show!)
