Only now i notice that this thread is about porn...
Okay, there is a niche for almost everything and customer`s needs can be quite diverse. However, porn is publicly available and producers should be aware of that fact. Everything that`s published also gives a statement! Dirty-talk can be a good thing up to some extent, but personally, i find it`s a turn-off when it is done too bluntly or degradingly insulting, and when statements are aimed at a group of people rather than just the actual performers. That`s a big difference!
Also, i feel there is no real need in "interracial" porn to be that explicit! Don`t a woman`s body language, facial expression and moans, without the need for acting - her natural response to being properly manhandled by a well-built black man - say it all?
