Yep. Back in the early 80s, I was in a naval aviation squadron stationed at NAS North Island in San Diego. My duty section had the watch one night and I was on duty after the rest of the squadron had shut down for the night and gone home.

I got bored during my watch, so I went up to the admin office to snoop around. I eyed the copy machine in maintenance control for a moment and then got a sudden inspiration!

I dropped my dungaree uniform pants, set the copier for multiple copies, crawled up on the glass, and started the machine. It began whirring and spitting out copies of my cock and balls, one after the other. I had started out soft, but as the copies came out, I could feel the warm light bathing my entire groin and my cock started getting harder and harder with each pass of the light bar.

Then, as I grew stiffer and stiffer, I began to feel a strange tingling sensation in my cock that rapidly intensified with each heartbeat.

Suddenly, without warning, I began to have a very intense orgasm! Shocked, I jumped off the copier, my throbbing cock shooting high velocity spurts of semen everywhere!

Fortunately, I didn’t get any on the copier glass. I think the entire incident may have lasted all of twenty seconds. The machine had made about a dozen copies of my cock growing more and more erect until I jumped off the glass at the point of no return.

I cleaned up the evidence that had landed on the deck, grabbed all the copies, making sure I got all of them, and stashed them in a safe space to keep them secure until I was relieved later that night. That was definitely one of my most memorable ejaculations, ever!

Sure, when I was younger, I could suck my own dick.
Completely 'hands free' ejaculation, right in my mouth.

When much younger I could cummm no touch just imagination

Yes it happened to me once.. I was having a massage when the cute girl asked me to touch her pussy and I ended up licking it for about ten minutes..I cummed without even her touching my dick..

Sat next to classmate how called it thinkingoff! He would whisper...Look! in geometry class and stain his pants!

Not since my 20’s

It is possible and not that much difficult. You have to be horny as extremely as possible. That extremely over excitement leads your dick to shoot your loads without touching your dick. I've experienced this so many times. It's happens more quickly if the main object to being over excited and horny is your wife.

Yes, it's possible.
Use someone else's hands:

I've cum without anyone including myself. But my cock was bouncing around cause I was bouncing up and down on her strapon.

I have cum hand free from getting fuck. It feels so good.

I love using the shower massage on my cock to induce an orgasm.

Yes - I've cum without my cock being touched when being shagged by big thick cocks.

I needed one hand to catch it all ...

No hands needed

E-stim works for me!

I cum regularly without touching my penis at all. I can do it many times in less than 5 minutes just by clinching on my butt plug. My record is 32 seconds. I know because I stopped the porn video when I came and it was 32 seconds in. I was riding this guy:

I had a big rubber cock with a suction cup. Stuck it on the toilet seat.Slowly slid my asshole onto the shaft and rode til i came.

No hands

I actually buck my hands making my nuts smack against me as they swing back and forth and it can make me cum

Had my first one when I was about 14. It happened the first time I made a girl cum while giving her head.

prostate stimulation such as Aneros anal stimulator takes practice but once mastered you will enjoy hands free orgasms
