Early 50s we lived on our grand parents farm in WV where enemas were always in the huge upstairs bath room laying on the administrators lap, mom would always make sure the lid was up and the seat down, but when we moved to Philadelphia and our only bathroom was small, enemas were now on our beds. Mom put a rubber sheet on the recipient's bed covered with a bath towel and went to the bathroom to prepare the enema. She would carry the enema to the bedroom and lay it on the bed, call the recipient who was told to remove pants and undies, lay down on our stomachs, if it was me getting an enema, I would watch in the mirror on the dresser as mom picked up the nozzle, lubed it, inserted it, then picked up the bag holding it up with one hand, reached for the shutoff, I waited for the click and settled in for my enema.
Here's the seat part.
When one of my sisters got enemas I would almost always "need" to go to the bathroom, passing their bedroom door and seeing them getting their enema, especially Diane who would always have both hands squeezing her pillow and grunting as she got her enema, and there was the bare butt run to the bathroom.
So it wasn't just getting an enema, I also enjoyed knowing someone else was getting one, was going to get one, or had just got one. Tess didn't care if I saw her, but Diane or Robin would holler "Marty just walked by the door" and mom would usually say "if you find enemas that interesting maybe you want one too". Sadly she never went through with that threat. I would say "I had to pee"! Mom replied "Be sure to leave the seat down and the lid up, your sister is going to need the toilet in a hurry"!
