Guys have you ever gotten a woody when you didn't want or expect it? Ladies have you ever intentionally tried to give a guy a woody in a potentially embarassing situation?
I remember once at a lake at a public swim area a group of us were hanging out swimming and relaxing in the sun. One of the girls had tried to dunk me but ended up with me dunking her. She begged me for mercy and under the water had wrapped her legs around my waiste and proceeded to rub against me until she felt I was very aroused at which point she splashed me and ran to very shallow water where I couldn't follow until things subsided and I wouldn't embarass myself. She had a good time taunting me from the shallow LOL
I still get non-sexual related hard ons all the time. Usually when I'm tired or bored. According to some research, when guys are relaxed, it opens up the blood vessels through out the body. Of course, when this happens, the blood vessels in the penis swell and give the hard-on.
....One of the first hair salons I ever worked at was mostly male clients..I used to have so much fun with them, until one day I caught a bloke wanking under my cape
