My take is that for we who are klismaphiles, enemas are a form of sex. Mommy giving junior and sissy an enema on Saturday night may be nothing more than a bowel cleaning. Somebody giving me an enema is a sexual act. So if I am giving the enema, because I am a klismo, it is a sexual act.
As we know, girls tend to be a lot less homophobic than guys, and less uptight about quasi-sexual intimacies. Sez me, anyway. Now personally, being a bi female, it would be very difficult for me to keep it professional with another woman, especially one whose bones I wanted to climb. If I were getting or giving an enema to another woman, from inside my eyes I would be already having sex with her... 'cuz I'm a klismo. . Maybe it's just me.
