Yes I have had an orgasm before while receiving an enema. Usually when a woman is giving me an enema I remain semi erect. I can take a lot of fluid so the bag may need to be partially refilled . Just moving the nozzle back and forth can cause me to stiffen. Then not more stimulus is need for me to come.
The very first time it happened to me was shortly before starting puberty. It was summertime, and we were at our grandmothers for our usual stay. I had been moody all morning when grandma finally got tired of it and told my young teenage aunt to give me a couple of enemas. I wasn’t exactly in the mood for a couple of enemas and fussed about it. That was a big mistake. My grandmother looked at her teenage daughter and told her, “Give him a good spanking first.” At that, I was escorted to the bathroom.
Once in the bathroom, I was told to remove my clothes and lay down across her lap. When the spanking was over, I had to stand in the corner while she fixed my soapy enema. Once she finished fixing the enema, I expected her to tell me to get in the knee chest position, but she didn’t. As I turned around, she was already sitting down, and told me to get back across her lap. While I was standing in the corner, knowing I was fixing to get a couple of enemas, my penis did what it usually did. It got hard as a rock. All she had on was a top and shorts, so I would be laying across her bare legs with a hard-on. I did as I was told, having just been spanking for fussing, I didn’t say a word. She started by lubricating my anus with her index finger, before replacing it with the douche nozzle. I had taken about two thirds of the enema, when I got a weird feeling in my groin and penis. It was unlike anything I had ever felt before. But boy, did it ever feel good, and I couldn’t stop wiggling around. All she said to me was, “Stop wiggling, you're tickling me.” By the time it was over, I had finished taking the enema. We normally had to hold a soapy enema for ten minutes, but she allowed me to get up after only five minutes instead. By the time I finished on the toilet, she had my rinse enema ready. But this time, she had me get in the knee chest position, instead of laying across her lap. I took the full rinse enema without the strange feeling in my groin I got the first time. When I finished releasing the second enema, as was routine, she put me in the shower and gave me a bath.
I didn’t understand what happened that day but was curious enough to say something to my siblings about it. I didn’t realize until much later, that I had experienced my first dry orgasm that afternoon. I don’t know if the spanking had anything to do with it or not, but I suspect it did. First, I got a spanking laying across my teenage aunt's lap. Second, she had me lay down across her lap again for my first enema, plus she held the nozzle in place the whole time. Our usual position for enemas was the knee chest position, but I wasn’t about to say anything, having just gotten spanked for fussing. After I told my siblings, they were just as curious as I was, so we started playing around trying to get a repeat of what happened. It didn’t take too long before it unexpectedly happened again, but this time I wasn’t laying across my aunt's lap with a douche nozzle buried in my behind. I was laying on my back using my hand, and the rest is history.
