Kissing compatability has always been a big thing for me. All of my fond memories of girlfriends past are of wonderful kisses. It heightens the bond and strengthens the meaning.
With that said, my wife and I were not compatable kissers from the start. We were very compatable sexually, but did not engage in passionate, lengthy kisses.
We're still working on it. We are both aware that it's a weak point and both want to improve for each other. In the meantime, it's funny because we tease each other for our blunders.
For the record, I'm the good kisser in the family! Hehehe.
