Dianne,

I've wondered that myself! Could it be an adopted characteristic based on the idea that to be feminine the male has to 'sound' (to their thinking) feminine?? It seems in the same sex situation there is a 'male' and a 'female'. Why is that??!! It's almost as if the couple is trying to imitate a heterosexual relationship. Its all very confusing to me.

Or, maybe in that culture the tongue thrust is a sexual symbol??? Don't want to be gross,,,
