Anderson never said she concluded Trump was the man based on media appearances. 
I think it's strictly *weird* that you find in necessary to contemplate Anderson's "position" and "anatomy" and all to conclude that somehow Trump could not have touched her without "reaching under." Your reasoning seems deliberately convoluted here but obviously it serves your purpose which is to belittle women such as Anderson and dismiss their claims and, concomitantly, to exonerate men like Trump. 
Your argumentation is banal and your motivations obnoxious.
