LADIES- How uncomfortable would you feel if someone you barely knew suddenly began blurting out really inappropriate things?

You’re married, he’s married… out of nowhere, he starts telling you that he really has a thing for you, he thinks you’re incredibly sexy and smart and you turn him on more than anyone else ever has. He says his wife would freak out if she knew how much you turned him on and how badly he wanted you. He wants you desperately and he really wants to see what you look like naked. You barely know him, and he’s coming on pretty damn strong, continually repeating how sexy you are and how much he wants you.

Would you just say “I’m flattered” and blow it off, would you feel mildly uncomfortable, or would it creep you out? I’m at the creeped out point…
