No. I had such a moment. But I didn't do it because I used to have a crush on my DM, it felt pretty awkward to me.
Other than that I haven't really done romance or seduction in tabletops.
Edit: I was being hit on by a fellow pirate who (didn't know at the time) was the daughter of the pirate lord of the dock we just shipped off. He was a cool guy though, one of the more likable ones.
