As to the question about men wanting to be present at expulsion:
My reasons for wanting to give my wife enemas/suppositories is that, for me, it emphasizes her softness. She is quite muscular (wonderful!) so, physically, there isn't much softness.
But, giving her a rectal laxative emphasizes the concept of softness in combination with her femininity and her most excellent muscular legs and bottom. She may not be real soft on the outside, but, she is really well-curved everywhere with beautifully large, firm leg and butt muscles. For me, the suppository/enema, emphasizes her softness inside. thus emphasizing her femininity.
I realize that we are all soft on the inside, and I love to be laxed, too, by all methods, with or without diapering. But. as I say, it emphasizes the relative softness at least in concept, of a female.awake or asleep. For me, being laxed emphasizes my human softness and submission.
Sometimes I receive a non-prescription drugged enema, which happens, for me, within 10 minutes of the 4.5 oz. sized, sedative enema.
I like the idea of her taking control of me, before my lights go out without warning.
I hope that this post is relevant in this discussion. If not, I'll trans-post it, wherever I'm tole :-)
