The anal sex scene alluded to in SUPREME POWER is not an anal scene, but, rather, is a doggie-style-fuck scene. --------------------------------------------------------------------------------
It horrifies me that you can tell that from just what was drawn there..."
I don't know why that "horrifies" you...but that's between you and your shrink...
I'm as equally qualified to make the assertion that the scene depicted a doggy style fuck as anyone else is to claim that it was an anal sex scene.
Further, I feel secure in making my assertion about that scene based on this--this man and woman have been isolated together for some time raising baby Mark. Why are we to believe that this act...which I am to believe was their only moment of any kind of sexual intercourse based on all the on-camera cues...was an act of sodomy rather than an act penis-in-vagina sex?
Let's take a show of hands out there, shall we? OK, all you women...you haven't had sexual intercourse in presumably upwards of months or even a year or so...so which kind of intercourse do you want? Vaginal? Anal? As a man married for over 15 years, I feel safe in saying that MOST women are going to prefer vaginal to anal sex.
