I am not a lesbian and I have kissed a number of women (see example above) That tongue thing is all for show. Most women in porn are not gay or not even bi. It is all a show and for money. Women are just different then men. We can pee and talk at the same time, hold hands in public, and kiss each other without it being a big deal. If they meant it, they would really kiss. If they are just trying to get you hard, they will do the tongue thing.
