The actual fight animations, or the fight sex stuff? The former shouldn't take THAT long, and if the latter are getting repetitive, you can avoid that content altogether with the charm (though that may end up locking you into a particular ending).
Yeah, that more or less is what it is. There might be a way to add the ability to skip, but it would be...very fiddly to get working if it existed. Will keep in mind if it becomes an issue for others though.
