The feeling when the liquid fills the colon is essentially the same. But as the saying goes: "Eat with your eyes".
I still remember the smell of the rubber of the bulbs, bags, hot water bottles and hoses. This smell has internalized in me. At the same time, this smell used to mean "danger". It was associated with the dreaded enemas, that I had to endure.
I also have to say that the feeling of inserting the old Bakelite nozzles is not comparable to today's plastic nozzles.
It may seem just a mental thing, but over the years I've acquired and collected a lot of old enema equipment of this type. Just the sight and smell triggers a certain excitement and memory of old times.
Well-preserved old douche nozzles, for example, still find their way up the butt, which excites me a lot.
That seems to be my fetish, which keeps memories and feelings from earlier times alive.
But as mentioned, this is probably just a matter of the head...
