If you do can't dance with girls at a dance or are just bad this is for you:
-first either just start grinding with her or make good eye contact and go up and start grinding( don't let rejection get you down) it happens sometimes to the best of us.
-second(if your not good) start with following the girl, put your hands on her hips and let her be your guide, you need to get rhythm and get a sense of a few ways of moving your hips with her hips to the beat.A.K.A Just don't hump her.
-practice on a more experienced girl one that dances wild, try to keep up and memorize those more advance ways of grinding
-after now having a general sense of dancing with a girl start leading the girl with your new acquired skills, nothing more sexy then a man how can move her and dance with her to her level or better
-After getting a little used to leading her listen to the song and add some variety at choruses of the song and don't let her predict you completely, you want her to catch your rhythm and don't make her lost but at the same time show her a good time and don't get her bored
-make up your own style to the music have a certain thing that makes your dancing different
(my personal favorite is slowing down for a few seconds emphasize the movement, then speed up again, this builds up the tension)
Some extra things to do from behind
-rub your hands up and down her hips
-slow down during a chorus(my favorite)
-speed up during a chorus
-grab her thighs(usually grab back if shes into it)
-grab her hand make her do a spin and grind with her from up front
-make out with her
Don't
just hump her
be boring
you can have a Bonner but a lot of girls find it awkward- if you want tuck it in with a belt
...anything else you guys think of tell me
have fun dancing!
