1) Bad breath makes for a really bad kiss... chapped lips can be remedied. Buy yourself some chapstick, and make sure you brush your teeth and tongue regularly as well as flossing.
2) You must not go immediately to sleep! She will want you stay awake through the emotional come-down (girls get this, but maybe not guys.) Spooning is usually the male's front side up against the girl's backside, and a hand on the boob is good. If she gets up to put on clothes, you should put your boxers back on. If not, then you can sleep naked. As for where and when to kiss, you can probably figure this out on your own, but I am assuming you are talking about AFTER you have had sex, so it seemslike that would be minimal.
3) People's level of tolerance varies. It may bother some people, but not others. Just think of that as a weeding-out process. Besides, if we can elect someone president who speaks as poorly as Bush does, I don't think you should have too much trouble.
4) This should NEVER happen. You should shower immediately before you have a date and especially if you might engage in sex, whether it be oral or vaginal. You should also soap it up before sex if you have urinated since you last showered. If you are not circumcized, be sure to retract your foreskin and wash under that, too.
5) I think it is good to start physical contact off slowly... touch her arm while you are talking to her, and pay attention to her reaction. If she still seems happy to be talking to you, then she didn't mind it, and maybe you can move in for a hug when you say goodbye.
Relax... I'll need some information first. Just the basic facts - can you show me where it hurts?
