Pornography is VERY educational, watching it you learn that:

Women wear high heals to bed
Men are never impotent
When going down on a woman, 10 seconds is more than satisfactory
If a woman gets busted masturbating by a strange man, she will not scream with embarrassment, but rather insist he have sex with her
Women smile appreciatively when men splat them in the face with sperm
Women enjoy having sex with middle aged, bald ugly men
Those tits are real
Asian men dont exist
Nurses give blowjobs to paitents
All women are noisey on the job
Double penetration make women smile
When a woman is giving a man a blowjob it is important for him to remind her to suck it!
Men dont have to beg
Women never have headaches
Women always orgasm when men do
