Hmmm...kissing...yum
Let's see....if I'm not enjoying what he's doing throughout time I'll alter his way of kissing through games and etc, I've done it plenty of times and it's helped them immensly.
If he knows he's not that good of a kisser but he's -trying- to be, then well, I'll make sure we move onto other "places" to entertain us for awhile.
If he thinks he's a good kisser or he's just not into it, well, his butt is outta the door, simple as that. *nods*
