How to turn him on in public?

When your near him hug him and find a way to have him hold you around the waist.

If he's turned on you'll notice he'll either not be close to you at all, his leg will be against your butt, or he won't be.

If he ain't then just play around and move your butt left and right a little and he'll feel it.

My girl does this all the time.

scratch his back, hold his hand.thats about it

whisper things in his ear- sexy and classic. Or slowly slide your hand on his thy and lead him on and then take your hand off. Nothing turns a guy on more than teasing!

I get turned on if a girl touched my side/ribs/lower back area.

Touch yourself. When he is looking touch your chest or neck with your finger tips. When you take a drink have your tongue touch the bottle first instead of your lips but be careful because if not done right you can just look like you don't know how to drink liquid. Lick your lips and look him in the eye when you put on your lip gloss. Anything that can bring attention to the parts of your body you find most sexy. The best part about it is you don't even have to be that close to him to do it. Just make sure you have his attention or he could miss out on your efforts.
