Wait, so your pubes got caught to your underwear when you stood up? loving ouch. asdf it hurts to think about. However, Back in 7th grade I've had my hairs wrap around y richard and somehow tie together. I see a hot girl and get a boner. INSTANT PAIN. All the pubes are being pulled at once and you have to look like a friend and reach down into your pants to pull the hairs appart from your erection.
I get this, but I don't reach into my pants because that makes you look like a freak/pervert.
Especially if they were to ask why you were doing so.
"What the hell? Why've you got your hands down your pants?!"
"Well, you see, I had a boner..."
