When pornstars, (I assume nobody else does this), scream "cover me" or "cover my __ in your cum" does this actually put the performer off? What if her tits were J cups? No one could cover those.
I find Ashley Long completely unnatractive when she dirty talks.
Much as I love Sara Jay, the time she told the actors to "use my face as a landing pad for your jizz" turned me off what would normally be a great scene for me that pretty face getting painted.
When a woman curses ,swears and talks dirty, this is the biggest fucking turn on for me. It affirms that she does what she doe with conviction and is just plain, old fucking exciting.
