Ok, just to make it clear what I'm saying, in porn, women generally get the short end of the stick when it comes to receiving oral. They either get none or a handful of minutes worth.
And when they do, the guys do a bad job at it, like sticking their tongue into the vagina, like a mini dildo. They ignore the clit, other erogenous zones, don't use their fingers, etc.
OP asked for lies porn told, as in things that wouldn't work in the real world. So I'm saying women wouldn't like any of the things in my post...
