Probably it could be said that all dancing has a sexuality aspect to it. I've taken many dance lessons including waltz and tango. Both these and others can be danced two ways, with a slight distance between partners and full-body-contact.
Full-contact ballroom dancing is indeed quite intimate and often symbolic but it is most definitely not grossly, overtly sexual. There is a difference. As Potter Stewart said, perhaps I can't define obscenity but I know it when I see it.
