Why not? Most of the dance competitions show two people who enjoy dancing. What's a relationship status got to do with it?

Horizontally?

What kinda dancing 😂

Innocent dancing should be cool, bumping and grinding, not so much.

Depends on your intentions

I would think

Yes.
In the world of dance, the dance partner is not assumed to be a sexual partner.

Gotta have an open mind and a level of maturity about it first lol

If you are the person's spouse, sure.

Too many variables here otherwise; fraught with peril, it is...
unclear the outcome will be; trouble might it cause.

Only if you plan to do something dirty and never tell anyone about it

Why not?

Nope

Only if you steal their lungs afterwards.

What if they kiss you and then leave you? 🙄

Yes. give him the nose wiggle

Only that stupid cowboy dance

Yes as long as you're not rubbing your ass on his dick or anything like that

Sure. Did he grab your ass while he was dancing with you?
