I think women are taught to find enmas sexual by mom, or grandma.
It started with the beginning of her period in very early teens.
Mom is helping her, by admnistrating and holding the enema bag. This is because back in her day she was taught the enemas helped with the associated monthly cramping from the periods. Then as the enema bag empties, mom says; you're told to "hold it", mom helps her with getting the discomfort of holding out of her mind by touching her daughter. The daughter then begins to associate the enema and its retention of the warm soapy water, with the sensual feelings from mom's touch.............Forever! This young girl associate the enema with sexual gratifaction. A N D for most women in that situation, it becomes a life-long deep dark secret.
I believe many if mant of these women were totally honest, they would admit often on occasion they have found themselves in bed with boyfriends, lovers, or husbands, doing all kinds of sexual acts. But NEVER got up enough nerve to say "I know your really trying hard to satisfy me, but I'd actually prefer a nice worm soapy enema".
Frankly, if they married these lovers, they have unfortunately traveled life never really being totally satisfied. I'm not saying they cheat, but I know they look at what they see as attractive people in the office, or at a cocktail parties, or even walking on the street. They wonder if that person would be receptive in giving them 2 qts of rather warm soapy water, just as foreplay....If the ever got the nerve to dare ask! I know they can't say that to their spouse, because the feared response would be "where the hell did that come from".........so the just keep going through life looking and thinking.
