I've had plenty of sex in my life and never felt the need or desire to spit or be spat on in the name of lubrication. Also, twenty + years of no spitting porn from the 70's through the 90s and then blam! Spitorama.
Some people like "poo play", too. To each their own.
That's a fetish---a specialized area that not everyone subscribes to/is turned on by/enjoys. Spitting is occurring across the board in modern porn, so it's not a matter of "to each their own."
Whatever. So, what about saliva freaks you out so much and/or confuses you? Porn didn't used to have so much squirting either, what's up w/ that? Why're people all into that now?
Saliva doesn't freak me out nor does it confuse me. I just don't find it sexy/appealing to be spitting during sex. Again, squirting is a specialization. Not every girl is squirting in porn but it seems like everyone is spitting.
