Don’t worry if the first kiss with this fellow is not the best kiss ever. Some guys (and girls) need a little bit of practice to get good at it. And do be aware that too much tongue, too soon, is not pleasant. If he starts in with too much tongue, just politely tell him that you’re enjoying kissing him, but you want to slow down the tongue thing for the time being. And don’t move too fast and watch out for the slobber (yours and his).
Make sure that your lips are soft, use a little lip balm, but then wipe it off, so your lips aren’t greasy or sticky. Make sure that your breath is fresh. I guess what I’m saying is if you aren’t sure when this kiss is going to happen, make sure you keep all of the soft lip/hygiene things going at all times.
