well mine don;t 'crotch grab'!
no need for crotch grabbing in street, and if you have seen it on one dance, please don;t assume that it is in all street dancing.
but if you are concerned about what it looks like on teenies, have you not seen the bollywood dancing (wrong name I am sure but have no idea on the right name....sorry).....that is all hip wiggling and belly rolling, and I have seen that on cbeebies (or used to....not had cbeebieds on in yonks, tis all hannah montana and HSM nowadays). it does not make me think it should not be done, or shown.....it is a form of dance, that is all.
IMHO
