I had some back problems in the early 90s. I was given a Tens unit for the pain and muscle relaxation. I wasn't long after I started getting better, that I began wondering about the Tens as a sex toy. I began putting the pads on my penis in different locations to see what the results would be. Later I started cutting the pads down until they were just a round piece of rubber. I started putting one in my urethra and one in my anus. Talk about a turn on! I really got a kick out of that. I began using both channels of the Tens for such. I even began putting one of the electrodes all the way down into my bladder. With a small current, it was quite a feeling! Then I began connecting the electrode pins to different metal objects. I've used the handles of wrenches, socket ratchets, socket extensions, and just about everything else you can imagine. Also I started making some sounds out of different metal rods and shaping them to fit like I wanted them inside my urethra and lots of times the bladder. Then I began connection the Tens to them. Sometime I have one in my urethra, one in my bladder, and the other two in my anus. If positioned properly, the ones in the anus can be positioned against the prostate for a wonderful feeling. I still have had very few 'no hands orgasms'; but have really enjoyed some really great orgasms with just a few little strokes of the hands. I've also made probes for my urethra and put heat-shrink tubing on most of it so I can place the bare part from the bottom of my urethra all the way through to the just inside the bladder. That and one against the prostate in the anus is so wonderful. I can turn the 'juice' up just enough to feel it slightly, then slowly advance it occasionally.
I started putting things into my urethra and anus at a very young age. The first thing I remember is putting the end of a little fireman's ladder between my foreskin and the head of my penis when I was about 3 years old. My mom caught me and told me that I shouldn't do such. I remember pushing a bath brush handle into my anus when I was about 5 years old while sitting in the bathtub taking a bath. I also remember about the same time sticking the 'knob' end of a hat pin inside my urethra. I also remember sticking bobby pins in my anus before I was old enough to start school.
My biggest problem is not having enough privacy. I live with my daughter and her family. I'd like to move, but I've helping them out financially and can't afford to do both live alone and aid them. My bedroom is next to one of the bathrooms and is passed every time someone goes into and returns from that bathroom. If it wasn't for that, I'd like to include a vibrator or two or three in my sexual sessions. Also I could have the equipment to do enemas and catheterization in the room. As it stands now, I can't do much more than some estim. I'd really like to have the freedom to cover my bed with plastic and have some things to push into my anus and all the way to the top of my descending colon.
I have had several things inserted into my rectum. I can get something about 2 1/2" in diameter into my anus, but can't get it higher. I have had about 1" diameter items all the way to the top of my descending colon several times, but would like to be able to use a greater variety of sizes to stretch and straighten the sigmoid curve better. I have a ball peen hammer handle that I have rounded the end so it is easy to get inside my butt hole. I can push it all the way until the head is against my hole. I can feel the end of the handle about an inch below my rib cage. I believe that's almost at the top of the descending colon. I have taken a 1/4" diameter cable, doubled, and pushed it all the way to the bottom of my ascending colon. It's a real turn-on to be able to accomplish something like this!
I have had bananas, with the peel, inside me numerous times. Also carrots, cucumbers, zucchini, and other things in me. Sometime the bananas will go way past the sigmoid! I can feel them at the top of my colon. Sometime they will stay there for several hours before they descend to be passed out. I have used peeled bananas, but they are a big more messy and harder to get inside without being squashed. I don't remember having more than one banana inside me with the peel; but have had 2 or 3 in me at the same time a few times.
I am straight. I've never had a 'gay' relationship. I don't knock it, just don't care to do it. I've often wondered what it would feel like to have someone ass fucking me. I might change my mind if I tried it. lol I'm also not into diapers or scat play. I like to take an enema occasionally, but mostly to clean out to make more room for insertions.
I've read a lot about the different estim boxes, but don't intend to spend the money for something different. I have bought several different Tens units, but they are nothing like the old on that I've had since the early 90s. I haven't found another one that has the same pulse, frequency, and modes as this old one.
I can only get about a 1/4" diameter object into my urethra. I haven't really tried to stretch it over any long periods of time. I know it can be stretched, but when I got it stretched to about 5/16", I let it shrivel back down to 1/4" because I didn't continue the exercises.
I know this is more that just about estimming, but wanted to give a little background about how I started getting into these things.
And by the way, I'm 74 years old. Been widowed for about 10 years.
