Women equate kissing with the overall quality of the man. Good kisser equals good man; bad kisser equals bad man. In order to kiss like a truly world-class lover, you've got to be prepared:
Are you clean shaven or rough and ragged? Women seem to love to look at a man who has that 3-day-old rough look... but... don't want is "scratchy" face rubbing hers. If you have some growth, be sure to keep it close cut, and be sure to not rub her soft face when you kiss.
Do something with your lips! Start using a lip balm. If you work outdoors or go
dating- before you get there, during a lunch break, and after you leave for the day. If all else fails, put some petroleum jelly on those babies at night when you go to bed.
Check your teeth. You don't have to have that "glow-in-the-dark" brightness... but... dingy or yellow teeth are an instant turn off to women.
Check your breath. You mint or licorice as much as possible or other mouth fresheners will do. It's not a difficult thing to have clean breath.
Check her "receptiveness". Is she sending you signals she's ready for that kiss... or... are you being your usual self and just jumping right to it the first chance you get?
