You're sitting with a girl, or guy if you swing that way, there's good conversation flowing, both feeling each other, and everything is going smoothly. If you've done anything right, she knows you're interested, but at this moment, you're having trouble building a sexual connection. My idea would be to compliment her smile, girls like compliments at the right time, correct? Instead of ending it there, say something along the lines of "You're a good kisser aren't you?".

This could start a more sensual conversation if you use it at the right time/tone of voice, and gives you a clear way to kiss her.

I've never used it, but I thought of it after having a hard time to sexually charge conversations and initiate making out/kissing.

What do you guys think?
