I can understand how you feel.
From reading this board I have learned that several people have this rule. So its not unusual. People like to keep certain intimate gestures just between them.
We will only cuddle and sleep (as in Zzzz...
) with eachother.
I, however, would not be comfortable playing without kissing.
I find kissing erotic and love that part of foreplay-- I don't think I could get aroused enough to play without it.
I am orally fixated, though. facelick .....LOL!
But you do what feels right for you.
Don't subject yourself to something that makes you uncomfortable.
Its all about pleasure!
