I read the posting 'Feelings' with interest, and it triggered my memories of solo sex as a boy. Here is my rendition.
I masturbated from an early age, 5 or 6, mostly by rubbing on things. It started on the support poles to my swing set, and graduated eventually to my pillow and teddy bear. But another method I liked was laying naked outside in the sun, using my hand, lubricated if possible. I was probably 10 when I first did that, and though the opportunities to do that were limited, the memories stay with me.
My family vacationed in Maine every summer, and I did a lot of exploring in the nearby woods. I found some remote clearings in the woods that were perfect for me. What I liked to do was sneak my underwear off in my room and go around in just my shorts all morning until the sun warmed up. The anticipation of what I was going to do was wonderful, and my penis would get very sensitive and half-hard. When I was ready, I'd slip my tube of vaseline into my pocket and tell my mother I was going exploring, and walk slowly through the woods to one of my clearings. I would usually slip my shorts off on the way, and be walking through the woods naked, with a little boner leading the way. The fear of getting caught added to the excitement, though I never saw anyone else in those woods (I did hear people on occasion, though).
When I got to the clearing I would lay my shorts down in a sunny spot and sit on them, then lay down and play with my penis for a while, getting it really sensitive. When I was ready, I'd lube up, and jack off slowly and deliciously, and eventually have a great orgasm out there in the open. I enjoyed those sensations so much that I would think of them while masturbating the rest of the year, and fantasize about the sessions I'd have the next summer.
I read a post some time ago about a guy who worked at Philmont Scout Ranch the summer he was 17, about how he would do the same things while on solo hikes on the way back out of the back county to base camp. Funny thing is that I used to do exactly the same thing. I worked as a Ranger at Philmont, too, and on long hikes I'd remove my underwear and hike in just my shorts, getting myself all turned on for a good session in the woods. When my penis got to the point it was driving me nuts, I'd leave the trail and find a small clearing in the forest, strip naked, and slowly masturbate to a wonderful orgasm.
Oh, those are fine memories. Ones that I jack to many years later.
