I'm trying to think...
but for me, enemas given male to female, where there is some realism....where the girl tries to "negotiate" so that she doesn't get them; where the reactions are not faked. Where it's not "porn."
Where the girl receives enemas she doesn't want, and begs for it to stop (one side of my personality);
This is part of the female psychology as well...I found years ago that women often (and I suppose men) want/don't want things. Almost as if being "made to do it" is an erotic stimulant, in itself, and being forced is part of the excitement. Some of it comes from the desire to be "proper," so if she argues, cries, fights, she can give herself permission to receive this from her Doc/Master/Lover; some of it comes from the desire to be controlled that submissives typically have.
I DO find watching men being given enemas by a pretty girl erotic--but only sometimes, but I'm not much into dominatrixes. I'm much too "Dom" myself for that, and always seek to control the situations I'm in. I do love enemas, though, and so I like both the giving and receiving.
And then I like to see...
where the girl secretly wants this, gets excited about them, and even though she's treated with firmness, has a great time, because she's anal-erotic, loves to be controlled, and doesn't have a hangup about the "weirdness" of the whole thing.
Pretty over-analytical, right??
