here is a question for all to ponder.

If you are going to kiss a person, what is the difference from a safety perspective.  If you are going kiss whay not go all the way and do either LFK or DFK?

I'd assume the exchange of saliva.  Guys know, I very rarely kissed anyone, but if I did it was closed mouth, no FK. (Believe it or not, I've been like this in my "real life" too.)  Since we are with so many people, I just assumed by not kissing, or "pecking," it would minimize my chances of catching colds or other viruses.  

That's my reason.

Once I allow the intimacy of total access of my mouth,then what's the harm if she wants to roam around in there exploring with her tongue.I equate no tongue to making that long trip to the moon and not even bothering to get out to walk around or stretch before you start the trip home.

If you walk around on the moon without protection, you will die!

Maybe want to use another example?

If you're DATY you might as well DFK.

Which one shall we do first?
