Most TER reviews mention a lot of DFK in the session. I like it a lot too. But in porn, one hardly sees it. Many porn scenes have none of it. Those that do, have it for less than 30 seconds.. Thoughts?

My guess is because the girl is too busy doing other things with her mouth.

I would think most aren't looking for that, there's only hard core porn, and the nightly news they are obsessed with ATM.

Your Ripple must be running low..

Back in Australia in the early 80's a lot of the hookers I worked with did not kiss as part of their service, because they wanted to keep something intimate to be special to share with the SO that they didn't do with their clients.  
Perhaps, this is something similar.

Kissing isn't porn worthy.  Everyone does it in public.  You might see it in the movies and on TV -- but mainly when someone is kissing someone they shouldn't be kissing, such as an affair, or other forbidden love.  

Yes you are right you can find people kissing almost anywhere. Which doesn't make sense when the argument can be made that kissing is more intimate than vaginal intercourse, something you rarely see in public.

Watching DFK does nothing for me. DFK isn't something I ever really enjoyed in my life. Light kissing to get in the mood and beyond that I'd rather get to the fun stuff

Except for girl on girl porn where guys can get off on two girls making out, most porn focuses on fucking and sucking, not "intimacy", which IMHO is why there is so little kissing in porn.

Unless it's just ladies, of course, and most girl/girl porn will contain sequences of this.  Otherwise, DFK isn't that hot to watch.  I can see that in most regular movies, and can experience this in real life and hobbying without difficulty.  

Nope! Even in the 80's there were plenty of porn stars (it's prostitution outside of California) who did not like to kiss because it was too intimate.

In the more erotic porn vids from Xart and EroticaX, etc

The new generation isnt big on legit intimacy....

and find it a great turn on to watch, mostly because it is so unusual to see in porn. There's lots of reasons that we can assume or that we've heard first hand from porn stars, I could care less.
