As for girls liking Sodomy, that may very well be true for a few girls. Apolonia comes to mind. I can't remember if she did it here but she sure seems into it elsewhere.
But in this case, I think the point trying to be made is, it's not IF they "LIKE it" personally but how much has to be paid, to see them do it on camera. My understanding of the porn business (very limited though it may be) is that it is a "pay to play" type of business. In this case I what I mean by "Pay to Play" is that, the more explicit the acts that are asked of the model, the more she (or He) gets paid. Teasing is less than nudity, nudity is less expensive than finger play and toys/vaginal insertion is more than finger play etc. I would guess that Anal is probably somewhat more expensive than toys etc. which I think was part of @EverthangForever 's point.
The other part of his point seems to be that it is not sanitary/medically healthy in any way shape or form, no matter how well she cleans herself out beforehand. I agree wholeheartedly with that opinion but that opinion is probably jaded by some of the things I have had to do during the course of my employment. Ugghh.
For me, along with not being exciting, anal just feels "Nasty" to me, knowing what normally comes out of that hole. That may be part of what excites others about it, I wouldn't know but it also seems a little on the degrading side to me to ask a girl to do that to herself, but that is only my personal opinion.
If others want to see anal, they can request it I suppose, it won't be me and like @EverthangForever I don't care to personally subsidise it either. I have enough trouble supporting my own porn habit... 😉
