I got a semi on the treadmill. x_x The head of my cock has been REALLY sensitive lately, because I haven't felt good enough to jerk off (I've been sick since today last week). After about a minute of running, hoping it would subside on its own, I took a seat in the corner. It stayed for a good 10 minutes. x_x Anyway, my question is this. How common of an occurence is this? I remember reading about runners (on this forum) getting erections while running through parks and such. I've never heard of or seen this occur ona treadmill... until it happened to me today. No, I don't wear a jockstrap. Anything that binds my meat, in the least, causes an erection (granted, not as noticable as one without binding but the bulge becomes embarassingly large). And no, I'm not asking for a way to fix this. The answer to that is that I need to let a load out.
