SPERM!

Who else had a microscope when you were a teenager? If you're a horny adolescent with a 'scope that promises 800x magnification, sooner or later it'll occur to you to dab a little bit of your freshly-pumped jizz onto a glass slide so that you can get a close-up look at how your ''boys'' are doing. I remember peering through the eyepiece, watching the li'l spermatozoans from my own testicles thrashing around -- the tails were just blurs, they were moving so fast, so the sperm cells looked like little bright twitching dots with this... vibrating blur trailing off of one end.

I've always been fascinated by my own semen, whether I was looking at it through a microscope or not, and I guess most guys feel the same way. In my earliest masturbatory days, I would jack off on the toilet and spooge into my hand, but by the time I started high school, I had discovered the pleasure of stroking my erect cock while lying naked in bed and shooting the semen on myself. The feel of the slippery white jizz landing on my torso became increasingly important to me as I got older -- it was like a punctuation mark signifying the end of the masturbation session. I don't remember how old I was when I first tasted my own cum, but I do remember many a time when my high-school stroking would end with me flipping my legs over my head and planting my feet against the wall so that I could ejaculate right into my mouth.

Haven't outgrown that, either...
