Most of it all happens naturally, but there are a few pointers that I can give. Just close your eyes and let your lips lightly touch each other. Don't rush into it, but don't always draw back or be too timid. Don't start with your mouth open because that just ruins the moment. If you want to do tongue, start with your lips closed, press them together a little (don't shove it), and when your lips are touching, slowly open your mouth and let your tongue do its thing. Try not to eat his face from the get go (well don't do it anytime really, but especially not from the beginning), so start by making it sweet and slow until he starts to get into it more. Hope this helps.
