this is the reason you're supposed to "leave room for jesus" when dancing. the evils of dancing have been propogated by religious beliefs directly because of its known proclivity towards initimate behavior.

On the contrary, seeing my partner being comfortable and able to express intimacy is a strong positive signal of their ability to form a secure attachment with me and other people dear to me.
