Memories of all our enemas gravitated to sitting on the toilet trying to take an enema. Don't remember how successful they were. So decided to duplicate the process.
Except used an ezm balloon nozzle knowing that my sphincter isn't as strong as when I was 5-8 yo.
Well it took two small enemas and then raising the bag to 5 ft above my anus to get the water in. Definitely not the best way to take an enema.
However, it did take a longer time, so that made it more enjoyable, plus the air in the bowel was pushed higher which added some attention getting cramps.
Sitting also lends itself to less awkward wanking.....😉
Try if for a change of pace....let me know the results
