Liz Ocean and Erika Mori are examples of pornstars. Generally speaking, girls are highly socialized—sometimes even overly so. Judge for yourself: will one girlfriend decline to invite the other to come see her in the evening if she has sex with her favorite guy, even if they go to the bathroom together? A girlfriend who will support a friend's dick and steer him in the proper direction can never hurt in such circumstances, and this is true by definition as well!
