I have many years of masterbating that might be of interest.
I was fourteen years old. I had been having some strange dreams that I could not fully remember. One morning I woke and casually reached down between my legs and I felt something sticky and wet on my sheets. I had no idea what it was but I suspected immediately that my old brother probably dumped something under my covers while I slept. I immediately yelled at him, 'what do you mean, putting stuff in my bed!' He looked at me and then it dawned on him and he said, 'well, little brother, I think you have just become a man.' I was really surprised and shocked at what he said, and in such a nice way, because he usually just yelled at me.
'Lets take a look' he said, pulling back my bed covers. He looked at the yellowish-white stain and at my pecker that still was dripping something I had never seen before and he said 'boy, you sure shot a nice load for the first time!'
I asked him what he meant and he then told me about hard-ons, rubbing and pumping, orgasms and why it was perfectly natural and that I now could join the rest of the adult world in pleasuring myself and someday someone else as well.
I headed for the bathroom and looked at my body in the full length mirror on the door. My cock hung down in front of my balls like always, but then I began to feel something happen. My nuts began to churn about and my prick began to swell, veins sticking out on my shaft and uncut dick began to stick up and out, quivering and throbbing. I slowly began to experiment, tugging slightly at my foreskin and releasing my bright pinkish, reddish, cock head. The first few pulls gave me a little pain, but it was the most delicious, mind bending joyful pain I had ever felt. Instinctively I put some saliva on the stretching flesh and soon the head of my pulsing prick popped out and I squealed, gasped and giggled.
I felt a sense of power and pleasure as I began to pull my foreskin over my glowing gland. I began slowly but soon picked up speed until I was panting and spit dribbled from my mouth, my eyes rolled back in my head, I grabbed my shaft with both hands and with a yelp and groan I shot five ropes of whitish cream onto the toilet seat. Wow! What a totally glorious feeling. I rinsed myself off, pulled up my shorts and went back to the bedroom and told my brother what had happened and he said, 'I can hardly wait to show you a few tricks I know.' He did just that, and our sessions were memorable.
