Here’s a bit how the child, intent on achieving a goal will zealously search out that which is needed.
Or how simple observation and a perverted mind come up with shocking ideas.
My dad had a lamp in his office by a reading chair. It’s was 80s modern, just a 5’ tall silver metal pole with a rectangular adjustable light fixture on top. The bottom of this pole merely had a 5-way joint/connector. The pole went into the top, and 4 cylindrical medal rods stuck into each of the others. Kind of like the bottom of an IV pole, but no wheels or design - just 4 metallic rods with a single rubber end cap.
I honestly don’t recall if I sought this out, or happened to notice it one day, but the rods on the bottom were removable, held in by a simple pressure screw. They were about 6-8” long, perhaps 3/4” in diameter, and solid metal.
Well, this one summer when I was around 12 or 13 I was being hit by hormones and enjoyed “exploring”. We’d just moved into a new “old house” and one of the bathrooms had a bidet installed. Boy did I have fun with that… I’d turn on the water to a nice temp, just bubbling up about 3”, then sit there and enjoy the warm sensations on my tush. Then I’d crank up the flow and let it give me a bit of an internal cleaning! I loved the feeling of the water effectively powering past my sphincter into my rectum, I could even feel the pressure on the anterior rectal wall.
So, thinking it was time to try something more solid, I fetched that rod from the lamp, headed back to the bathroom, and closed the door. I proceeded to lay on my back, bottomless of course, and tossed my knees up over my shoulders, leaving my little rosebud completely open and exposed to the elements.
I toyed with my back passage a bit and noticed if I “beared down” - without knowing what that was except to contract my muscles as though I were trying to defecate - it would open up, and stay open as long as I left those muscles relaxed. Then I took the rod and slowly inserted it. It went in quite easily! I kept playing, and as my anal sphincter relaxed more and more it eventually was open wider than the diameter of this heavy metal rod I was inserting! But it only went in about 4-5 inches, more or less, because it ran into the same anterior rectal wall that the bidet would hit.
So, for a while, I had a lovely new toy to play with. I even got to the point where I’d “drop” it in there just to feel the thump it would make on that rectal wall.
In retrospect, it’s pretty remarkable what crazy activities the mix of curious naïveté, creativity, way too much free time and a sudden onslaught of hormones can produce!
