I'd say it's as sexist as any form of porno. Some women would be disgusted, some indifferent some enjoy it.

If it helps you sleep at night, then at least take note that in many BE / GTS etc stories it is the woman who is in control / the provoker, so at least it can be progressive in terms of gender roles (where in the vast majority of normal pornos the man is the dominant one).
