How I first masturbated
My family rented a small vacation cottage, which was actually an old barn that had been converted into a summer place. Behind the barn was a field of tall grass and through this grass about 100 yards away was an old abandoned chicken coop. This structure with a sloped roof was isolated with hardly anyone ever going there and the roof was low enough so that I could climb up on it and lie there, facing away from the barn, pretty much invisible to anyone nearby with out their plowing through that field.
I was at an age when I had started experiencing erections and feeling those glorious arousing feelings in my genitals that were not really understood by me but were compelling me to play with myself and induce them. I found that on a warm sunny day I could slip out of the house, through the field and up onto the roof of this chicken coop and lay on my back as I took off all of my clothes, spread my legs wide apart and felt the warmth of the sun and the cool breezes caress all of my sexual parts. I didn't understand much about what all this meant but I did sense that it was dirty and that if my mother caught me I would be totally humiliated.
Of course this sense of danger and of doing something shameful made it all the more exciting and arousing and I became a bit obsessed with it looking for any opportunity to masturbate that might present itself. I would lay there and just rub my hands all over my genitals and crotch and I even discovered that it felt good to poke a finger at my asshole, which of course reinforced the idea that I was doing something dirty. I loved the feelings but I didn't know enough about how my sexual parts functioned to realize that if I rubbed hard enough I would have this thrilling spurt of an ejaculation.
So I would lay there just caressing and pawing myself, spreading my legs to enjoy the wonderful feeling of being naked and exposed. This is my first masturbation memory and the beginning of a lifelong addiction to compulsive masturbation that has continued unabated to this day some 65 years later.
