Why porn movies dont have subtitles...

Shhhhhhhhh... well most of porn movies I/We have watched(Yaaa we all breathe) dont have subtitles. So I decided to do some research on that and came with few reasons below.

# May be after all the hard work nobody had time to write subtitles...
# May be they consider it more like National geographic/Discovery programmes where all we
can hear is birds singing, animals roaring and some weird sounds coming from animal acts,
we dont need subtitles for that. Since humans are also animals, hence the theorem proved that porn movies dont need subtitles.
# 'Who has time to read subtitles while watching such movies man?'
# last and conclusive reasoning is 'whats there in the movie to put into words', its like A picture is worth 1000 words and this is a movie!!!

Subtitles in movies

Today i found out one real good advantage of having subtitles while watching a movie. You can clear your ears while watching a movie, need not pause because you cannot hear while cleaning. Thats what i call efficiency, doing two things at the same time. Next time an interviewer asks me so called competancy based questions, like 'tell me a scenario where you increased the efficiency by doing two things at a time as well as being creative', bingo! right on target, my answer is ready. I was creative enough to use the subtitle and on top of that efficient. Ahh! wish the answer is accepted.

PS:- One weird thing I noticed is porn movies dont have subtitles!!!... Any guesses? Let me bring that in new post...
