I remember learning to masturbate for the first time when I was around the age of 9. My best friend, who lived next door, and his little brother were over at my house just goofing off with our Transformers/G.I. Joe's when we started talking about girls. My best friend who was about a year and a half older than me and a bit more mature said that he had to 'jack off' sometimes when he thought about girls and sex. Not knowing what 'jacking off' was I had him explain: He first said to get some lotion and smear it on your goober, then he made an 'OK' hand gesture where the index finger and the thumb made a circle and said to go up and down on your pecker until you 'spazz' so to say.
Bewildered and immediately after they went home, I went into my Mother's bathroom, located some lotion and proceeded to masturbate for the first time. I remember laying on my parent's bed, looking up and the ceiling and thinking 'holy crap this is awesome'! Obviously I was in for a big surprise when all of a sudden this urge-to-pee like sensation took over; my body convulsing and then WHAM!
I had an orgasm.
I laid there panting; my penis in my hand thinking this is too good to be true! Obviously multiple masturbation sessions ensued and plenty of them were with my best friend and his little brother, but that's another story.
