When i was 5 i was hoisted over my mothers knee, shorts pulled down, and she pushed a vaselined finger up my bum. She then pushed a piece of soap up me, it stung like hell and i remember crying, but it made me run to the loo to try harder to shit !
I never had this happen again , not an enema, but I've used soap and enemas as a sexual stimult all my adult life. Alone and with others.
Right now i don't have anyone to play with, so any girls in the UK want enema fun, you know who to ask!
