I have really not seen enema-caused erections.
I gave my now-husband a round of enemas when we were engaged just to test his reaction, and see if it was going to cause an issue in our marriage.
That was the ONLY time I have so far given an enema to ANYONE else.
I didn't see any meaningful erection in that session. I have learned since that a partial erection can occur, where it does not dome all the way up but still enlarges a little That's exactly what happened.
We can only go where life leads us.
Neither of my twin daughters has needed an enema or suppository so far. They have now reached school age.
My husband knows everything about my enema taking.
He HAS given me a few sexual foreplay enemas, in which I was in Simms Position and he gave me an enema. He got a full erection during injection!!!
Just about a year ago now we did one like that, and I told him, "I'm always on the receiving side of these sessions. I think it's time you take your turn!!"
That was the ;last I heard of it!!
We'll see where that goes. Sooner or later what's going on now will wind down and we will want a little variety. We will see how enemas fit into that when it happens.
