You'd have to be very good-looking, extremely confident and ridiculously charming... even then they would be "creeped-out." So you'd have to follow it with some seriosuly alluring chat.
The fact that you made this thread suggests you're not confident enough to do this (no offence).
Edit: Woaaa!! After re-reading your post, I noticed you say "enchante" after kissing her hand??! Did you get the spelling wrong, or where you trying to be "charming."
