Climbing the Rope in Gym class.

[Sparky Kronkite]

The first time I masturbated - the very first time I discovered this - or came (pardon the pun) to the self-realization that "I was capable of this, this - orgasm," even though I hadn't heard that word yet - well I guess I was twelve or so. Sure I had experienced the "rope climbing thing." Hey, bet there's a big example of the difference between the sexes - I bet women (girls) don't get "that feeling," when they're climbing the rope in gym class. I wonder though. Anyway - my mom had one of those primitive (but new at the time) I don't know what they were called - vibro-belts thingy's - you stood there and they wobbled your ass around. I guess they were trying to shake off the extra weight. Anyway, mom was out, nobody around - I slipped my pants down and flipped around so's that the belt rubbed my orb. I turned on the switch. Man!!! You talk about an explosion!!! A young boy? First time? Wiggling and waggling at about sixty cycles per second. I tell yah - spunk flew everywhere. It was great. The world was never the same.

Imagine that.

I'll warrant the exercise room was never the same again either.

As for the female equivilant: horseback riding
Ever wonder why so many young girls have horse addictions and beg their daddys for their own? Now there's a story idea for ya...a 18 year old innocent who goes riding for the first time and is so overcome with her galloping orgasm she jumps the groom in the barn...
