First time for me was at boarding school when I was 10. We had open showers and I enjoyed seeing the other boys naked. Sometimes boys would get erections which was even more exciting. My cock seemingly was bigger than most of the others, even some of the eldest boys aged 12. A 12 year old took me to one side and said he wanted to show me something. One Saturday we went for a walk in the woods. We stopped and he asked me if I'd ever masturbated. I didn't even know what that was lol. He took his cock out and started rubbing it. He soon had an erection and was clearly enjoying wanking it. I was amazed, it looked great. He said you keep doing it and at the end it will feel great. I pulled my cock out which was already hard and copied him. It did feel so good! After a short time he came and shot a small amount of cum. I was spellbound! He said keep going. After a minute or two I had my first dry orgasm, sooo good! After that we would meet up regularly and wank together. We started playing with each others cocks and sucking sometimes too. He loved mine because it was slightly longer than his but much thicker. First time I had actual cum I was 11 almost 12. Great times!
I think it was the summer between 6th and 7th grade when a couple of my school friends walked by when I was sitting on the front steps of my house. They told me about how good it feels when you rub your dick and then a white stuff comes out. I was really uninformed about sex and my body functions. I had noticed that it felt good when I rubbed my dick against the sheets at night. With their explanation I carried it though to my first orgasm. Whew. Became a daily activity for many years.
