Are "auals" not supposed to get s from women nor men?

Auality is rare, but does exist. I would think that they still might get s from a variety of causes.....just like most men do. Most men have gotten one from thinking about a wide range of people, both from the gender that they are attracted to and the opposite gender. Of course, many won't admit this, but I do believe that it happens. I don't see why it would be any different here.
