you say you’re worried about harassing her. we need more context on why you’re worried about this to be able to give the best answer. If this is a professional context for either or both of you, the focus should be maximizing your professional rapport by reassuring her without mentioning romance. if it’s a very laid back workplace where strict boundaries aren’t 100% mission critical you miiight get away with something like “in a different life I’d like to know you a little better actually, but I think the most important thing for both of us right now is to keep this professional.” vs if this is an entirely personal relationship you could try something more like,"I’d actually like to know you better if you’re interested but I didn’t want to overstep.“
yeah I thought it was a fetish thing
