i can't dance for shit so i don't have this problem. i feel kinda weird when chicks want to dance with me and i just stand there and do nothing.
freaking cock teasers just want me get a stiffy and get embarrassed. well the joke is on them. my pee pee is so small that nobody can tell i have a stiffy.
i would say just go for it, if they don't respond move onto to somebody else. that's what chicks do.
