A friend of mine when we were still in junior high. We learned to masturbate together and it was a regular thing for a while until he moved.

I was 12 or 13, and my friends and I would sometimes go out at night peeping through windows,looking for girls and women. One night we were looking through a first-floor apartment window and saw an elderly black man lying on a couch in dim light, with what looked like a 10 inch hard cock that he was stroking real slow. Being typical young boy's we laughed and yelled and ran off, but that night, lying in bed, all I could picture was that cock! I went back to that window alone a few times, but never was fortunate enough to see him again.

My own is first memory. I had a female doctor growing up and I was always hard just from her examining me elsewhere. Obviously I was like a rock everytime she said pull down your pants, and the following penile/testes exam.

First time I saw another was 6 pr 7. At daycare a few of us had snuck off to show and tell.

Saw my first hard on at 9. It was impressive to see him go from soft to hard and start stroking it for me.

Probably in the first porn movie I ever saw which was called either "Babylon Pink" or "Babylon Blue". 19 or 20 years old.

i was around 9 - was older cousin's penis erect at sleepover - he was 6 years older than me. Also sa it from soft to erect and back - first time a saw pubic hair on a friend as well.

Besides my own--I was about 9 and watched an old guy jack off in the park

When I was about 7, I watched as my cousin who was 6 years older jerk his hard cock until he cum.

Mine was a cousins in the bath we were sharing.
He taught me to wank using soap and shampoo on my cock.
First cock I sucked off too.

Also had two school mates who got together with me to see who cum first with us all wanking together on a sofa and naked.
Had both their cocks in my hands many times.

When I was 13, my younger next door neighbour found his dad's stash of sex instructional tapes. He invited me and another guy my age to see what he found. After watching the first segment about how to fuck in the pool, the younger guy got bored and wanted to go do something else. Judging by the visible boner in his pants, me and the older guy were both really turned on and wanted nothing else but to keep learning how to fuck like men. So we lied to younger guy about going downstairs in a minute and sent him away.

The next segment on the tape was about how to eat pussy. I couldn't resist any longer and started to rub my hard cock through my pants. I could see my friend keep switching from watching the tape to watching me. I had never wanked in front of anyone before and would have normally been too embarrassed to. But the tape's next segment had a milf with the biggest tits I'd had seen getting roughly fucked in a threesome. I had this feeling that I just had to get my cock out and start stroking regardless of the other guy being there.

As I was turning to tell the other guy that I couldn't resist jerking off any longer, I was shocked to see that he beat me to the punch and already had a massive cock sticking out of his pants. I froze at the sight of my 13 year old friend's hard latino cock pointed straight towards me. All I could do was stare at his dick and think how it looked larger than the guys on the tape. Before I could say or do anything, we heard the younger guy coming back up the stairs. My friend stuffed his dick back in his pants and I stopped the tape.

If the younger guy hadn't come back, I wonder what would have happened.

I was 13 and my cousin who was 5 years older showed me my first playboy magazine. My first time seeing a naked woman too. I got hard instantly and when I looked over he had his dick out stroking it. He told to take mine out and jo off too. I came quick but he lasted for a awhile. His was the first hard cock other than mine I saw. Went on from there for other things I did with him.

Not sure if first time counts, but must have been around 11. Crawling around with a friend in a wheat field making trails and rooms. We needed to pee, so we each made a hole in the ground to lay over and pee. Some dry humping the hole and unsure how it happened but I do remember touching penis tips together. Neither of us were fully grown, but that was my first!
Second time, around 14, walked into dorm room and caught friend going at it whilst reading a book of porn stories! He was extremely embarrassed that id go running off and tell everyone he'd been wanking! Never did say anything and thinking back, it was a huge cock and yeah, Id probably have joined/helped had I less teenage hangups!
Still one of my fantasies to join in.

It was at about aged 9 or 10 that my best friend and I used to play with eachothers dicks. Neither of them was very big but they ceratinly got hard. We used to play a sort of doctors and nurses game where we each took turn to be the nurse. The problem was always dick related, and we both always got naked. The cure was always for the nurse to either suck it or have it rubbed back and forth between the cheeks of her bum.
The first hard mature dick I saw was at about the same age, I was with my older sister and her friends when the boy from across the street who was about 16 took us all into his back garden, dropped his jeans and underpants, and proceeded to jack off with all the girls and me stood round watching. That was the first time I ever saw a dick cum. It was a regular thing with him and the girls in the village and if I happened to be with my sister when he decided to do it, I went along.
