My girlfriend just asked me if i would still love her if she didn’t have any skin?? um...
With all due respect to your GF -- this is extremely ... searching for a gentle word here ... odd. What kind of hypothetical is that?? It'd be like asking my wife if she'd still love me if I had a blank where my face should be, which is sort of a proxy for asking if she'd love me if I weren't entirely human or myself. It's like confusing some aspect of her humanity with the whole of it.
If I were you I'd try to get her to unpack what's behind the question. Although I'd be a little afraid to find out what it is, I think it might be, um, important to sort that out.
