I think I mentioned this before, but could be fun if "hey why don't we go somewhere more private" didn't reliably end up with the predator eating you, but became a risk vs reward scenario where the predator might fuck you instead for a big relationship boost.
... Or fuck you and then eat you or AV you or UB you anyway, depending on circumstances.
Like maybe with Beatrice, it's a wild card until relations improve, or maybe there's always a slim chance you get eaten during/after sex, whereas Jasmine it's very slim chance she does sex at all without just eating you unless she's already with a full stomach (and even then she's likely to still work up an appetite), whereas Sigurd would only eat you during/after sex if she's very drunk when you go fool around.
