"Breakaway" singer, Kelly Clarkson, definitely feels kissing is personal especially when it comes to smooching. However, the 25-year-old singer has another reason for not kissing too many guys - she is afraid of "mouth herpes."

In the August issue of Blender's magazine the two time Grammy winning singer reveals that she's only smooched five boys in her whole life.

"I have major trust issues. I just don't make out with people. That's a waste of my kisses and time....Plus, I'm afraid of mouth herpes," she said.
