Not that long ago, but a few decades in the past, every home had an enema bag.  Sometimes, it was in a closet in or near the bathroom; other times it was kept hanging up in plain view in the bathroom.  It didn't matter either way: everyone knew that enemas were a part of life, and everyone got them now and then, just like having one's temperature taken.

I grew up at the tail end (so to speak) of the last generation where this was the norm.  Everyone in the family knew that when we got sick, we'd get an enema.  If we got constipated we'd get an enema.  If we got a cold we'd get an enema.  It was part of life.  When Mom gave me my enemas (I was a very constipated child.), it was no big deal, and there was certainly nothing sexual about it.  It just happened.

A few years after she stopped giving them to me, when I was in my late teens, I came across what was in those days almost an under the counter magazine: Penthouse.  They had a letters to the editor column, in which enemas as a source of sexual pleasure were mentioned.  As soon as I read this for the first time I knew: I would never be happy until I married a woman who loved to give me enemas as much as I loved to take them.

There are physiological reasons why enemas feel good, especially to men: the prostate gland.  Okay, that's only one reason, but you get the idea, lol.  A Vaseline-coated finger, followed by a Vaseline-coated nozzle sliding into us back there can't help but turn us on, because of the way it stimulates the prostate.  Also, once the enema starts, the warm water, flowing into us, warming and stimulating that prostate gland is heaven.  An erection is an involuntary reaction when we're given an enema.

Still, there are more compelling reasons why men need enemas.  Imagine a man lying down on his belly, legs apart, naked.  Or, imagine him naked, bent over, on his knees, shoulders to the mattress, legs apart.  Now, picture him with an enema nozzle buried in his ass.  See a woman, above and behind him, holding up an enema bag with one hand, the other hand on the end of nozzle in his ass.  Picture the water from that enema bag flowing into his ass.  Is there any doubt about who's in control?

He's naked in front of her.  She's used the nozzle to invade is most private, hidden, intimate hole.  She's filling it with water, giving her control over his most intimate bodily function.  He's getting an erection, and, if he's lucky, will get to mastrubate while he's holding in that enema, thereby giving him an intense orgasm, and also displaying the fact that he likes it up his ass.

Enemas are the best cure for constipation.  They're wonderful for general health and internal cleanliness.  And they make any man lucky enough to get them from his woman nice and clean back there, in case she wants to use a strapon on him, or bring home men to use his sissy ass.  They also establish that she's in control. :)
