I've alsways enjoyed cbt. Been doing it for many, many years. You see fellas I/m a lot older than most of you. Perhaps I ought to know better but... I always liked to use  an elastator on my balls. One or both of them. I got real hot as they gradually turned an ice blue color.  I even allowed them to turn cold before cutting the band that kept by manhood. Once, I had a difficult time cutting the rubber material. I really had to dig deeply into my sac to finally reach the elastrator. This gave me a taste for wewhat happens after the initial 30 minutes of elastration. I got a pain in my left leg and then one deep into my groin. It finallt felt like someone had kicked me directly in the balls except it was deep inside me. Not really a good feeling.   I have a very big ball sac that enabled me to push them back into my ass. Once placed there, I'd let my spincter muscles do the rest. It really gave me a helluva jolt when I'd come with my balls stuffed inside me that way. Still other times I'd use pins and slowly push each pin thru my nuts until it came out the other side. I was up to four pins in each ball. There wasn't much pai! n. In fact it was more difficult to push the pin thru the outer skin. Once you heard it pop, the rest was easy. Sometimes when I'd withdraw the pins a clear white fluid would shot up almost an inch. Once I tasted it. It was quite salty.,That too gave me a terrific jolt erotically. I was into pins also on my cock. Once a pin broke in half as I was pushing it thru my cockhead. I pulled out the broken piece easily. It took a pair of surgical treasers and a lot of digging before I was able to finnaly get the remaining piece. That sort of sobered me up and fast. I always had a supply of antibiotics so I mucked thru. Later I got involved in putting saline solution into my sac. Had all the right equipment and this was successful a couple of times. My sac really got distended. Seemed to hang down almost to my knees. It took about 36 hours for the fluid to be absorbed into my syatem.  After the last epidode of saline solution experience, I noticed a lump appearing on my right testicle.! Then it got sore as hell. Out came the antibiotics but this time it didn't work. The ball got bigger and bigger. Perhaps three times as big ast the other one. Finally I headed for a urologist. Told him I got hit in the nuts while chopping wood. I don't know if he believed me or not. After going thru all the tests, the doctor told me that the ball was beyond repair. He was afraid that cords, some of which were completely closed, atrophied he said,  might turn into gangarene. Much like testicle torsion. How would I feel with only one ball ? he asked. I said at my age I really don't think I'll miss it. Little did he know that I've always had a fantasy about being castrated. He scheduled the OR and on an out patient status he removed the useless ball. He have me a spinal. I asked if I could watch. He didn't think it was appropriate. He did, however, describe the procedure while doing it. I listened intently to the whole thing. The OR people thought I was brave as hell. I just wan! ted to experience this whole thing. After completing the procedure, he showed me the little pinkish white ball. Wasn't to impressive but what the hell! I was half a eunuch. He wanted to know if I wanted an artifical one to create a balance. Or in case at the swimming pool dressing room someone might notice. I said no. Actually I'm proud of the imbalance I've now got. Anyone can see it if they wish. I'm happy with my situation but am glad that a surgeon removed it because there's much to much that could go wrong. I've got a little scar where the ball was and also a slight scar on the inside of my upper leg where apparently he tied some of the cords off.   What about the other one? As Jack Benny used to say, "Im thinking. I'm thinking."
