Are Female Enema Lovers more prone to have anal sex than others?
Well, it's complicated.
As some of our women have stated below, no, enemas and anal sex seem to be an apples and oranges comparison.
Many men and women use enemas as a way to get ready for anal sex but may not necessarily find enemas erotic rather just a practical tool and a means to an end (no pun intended)- having clean anal sex.
As some have stated, a penis is much larger than most standard enema kit nozzles, so leaping into anal sex with only enema nozzle experience could be quite painful.
Having erotic anal sex comes with its own baggage whether it be for a man or woman. There has to be a warmup stage to relax the anal sphincter and open up before anal penetration. This may take lots of foreplay with inserting well lubed fingers first and really getting the person aroused. Or it may require lots of practice sessions well before one even tries anal sex for the first time. One may want to practice with graduated sizes of butt plugs or dildos and work their way up to the girth of an average penis size. This will give the receiver some experience and some sense of what it will feel like to be penetrated with a real penis.
So, if one does not want to try or is reluctant to take the steps to get ready for anal sex, then it is pretty much off the table when it comes trying it. Some people are anal erotic and enjoy many kinds of anal stimulation and penetration as well as enemas. But just loving the physical sensation of what enemas provide, does not necessarily equate to wanting anal sex. And the gate swings both ways- there are those that like anal sex but are not really into enemas for pleasure.
So, know what you do and don't like and stick with it. But if you do want to try new things, do a little research to help you decide if you want to try something outside your present comfort zone before making the big leap. That will give you the best chance to have a pleasurable and erotic experience.
