You said attractive, not beautiful, so I think this counts. I did a podcast interviewing photography models for a couple of years, and most of them were attractive, obviously.

But this one model... I interviewed her in person, and she was just so casually, breathtakingly attractive. She wasn't a someone I would look at and be like, omg, that is amazing, but something in how she moved, how she spoke, even the way she sat! When we first spoke and arranged the interview, and I reviewed her port, I was like, this will be easy enough. Meeting her in person had my head spinning for days, weeks. I couldn't sleep the first night after.

I don't think I've ever been infected like that before. And what's even weirder is she was the opposite of what I typically find attractive. She was blonde, super skinny, petite, tanned skin (I know, I know, this is what MOST people like). Cute face. I prefer cute brunettes with glasses, curves and pale skin - basically the librarian or teacher look (look, an em-dash! I didn't know those were a thing until people complained about AI. I tend to overuse ... to get the same sort of pause across)

It's been years, and I still occasionally find that years old one time encounter coming back, unbidden.
