My first orgasm occurred at age ten when I was climbing a metal pole on a playground. I had been pulling myself up with my arms and then tightening my legs around the pole while I slipped my arms up and continued climbing. When I got near the top of the pole, I experienced the wonderful, thrilling feeling of my first orgasm. I held on to the pole very tightly while it happened, and then I slid back down and sat on the corner of a sandbox to think about the experience. I was very excited by the discovery.
I just wanted to throw a "5-hand" suggestion your way, as it is a shame this thing doesn't have the publicity it deserves. There is a children's toy out there called the Super Mondo Ball. You should be able to find it at most local toy stores or science-museum gift shops. It feels absolutely fantastic with the addition of your favorite lubricant. Benefits:
Go to a toy store and buy one of those soft, super-stretchy rubbery wigs, the kind that have the soft spikes all over that make your head look like a sea anemone. They cost about $6. (They're not actually rubber but some kind of modern gel-rubber stuff that stretches very far without breaking.) Turn it inside out so the spikes are on the inside. Put about a half-teaspoon of water-based lube inside, work the lube around the spikes, and then slip your penis inside. All those soft, lubed-up, spiky fingers feel amazing all over your penis.
As an adult male, I'd like to say a few things to those boys and/or young men who struggle and question. As males, masturbation is completely natural and normal. Yes, often "religion" teaches against it; our parents also ignore it. Guys, the fact is that every parent of every boy of a certain age has wondered what was taking him so long in the bathroom. They both know, especially Dad. They probably don't say anything because their son growing up, in the throes of sexual development, and that makes parents uncomfortable. How soon we older people forget.
