It's well-timed that I found this thread when I did! I'd almost forgotten of the phenemenon of blue balls until a little over a week ago.
Thing is, I've been, uh, mostly "flying solo" for a while, which tends to relieve the teasing issue (I mean, you know your hand's gonna put out). But, I went to meet a "friend" a couple of Saturdays ago, and we made out for a solid two hours before I started noticing a familiar "pain"...sure enough, the torture of my early teen years: blue balls!
Of course, that was quickly taken care of, but I'd forgotten how horrid it could be!
