Hi - There are so many reasons facials turn me on.
I think fundamentally though - the act of a woman, willingly displaying cum (the most primordial sexual fluid) on their face ( the most visible and vulnerable place on her) is the root of my lust.
it is such a juxtaposition of the product of sexual lust (cum) and the most visible area of attraction (face)
The face is where so many thousand things can be expressed without words, each subtle expression speaks volumes on whether she is happy, sad, worried, overwhelmed -etc.. and I am attracted to each expression at different times.
Sometimes I love seeing a innocent sweet young face, with a load of cum on her, placed respectfully.
sometimes (most of the time!) i like seeing a woman get plastered under many loads, with a more overwhelmed or excited face,
and sometimes I like to see a woman struggling under the loads, like clearly she is not having fun. The act of a woman being completely subordinate for a man turns me on(I used to worry about liking this sort of porn, but have decided it's just a part of my unexplained sexual desires)
In reality, I am very respectful - and usually never get to do a facial, as per woman's request.
It depends on my sexual moods I suppose - hope this sheds some more light onto this weird practice!
