It sort of plays with arousal a little in the design of the nurses, but that serves the story and is also creepy, you're not supposed to be aroused by the faceless bloody-bandaged booba enemies, at least not 'cleanly'. They and Pyramid Head are the warped expressions of James' desires.

I don't know if their inclusion was intended to become a rorsarch test of the players themselves, but that's sure what happened. Now that I think about it, their design is great for that, it says "Here is some prominent cleavage and about 36 indicators that something is terribly wrong and dangerous, if you can ignore all of them and get horny for the cleavage then you are very close to being the worst version of James."

And it's one thing to sexualize the sex monster. But to then insist on sexualizing a human character with a personality who is in great pain from a lifetime of objectification and really wants to not be sexualized, to then petulantly stamp your foot and insist on the righteousness of your crusade to morph her into something you can whack off to... It seems like it's more about the power at that point, the power to take away someone's ability to refuse to be consumed as a treat.

Just for the sake of the people around them, I'm glad these guys will never have a relationship.
