It can mean a few things. Firstly it could just be that he over-heats easily and his body normally sweats to compensate for it. Many athletes sweat profusely. Secondly it could be that he is out of shape, and therefor making out makes him heat up and therefor sweat. Thirdly, it could be that he is in shape but just gets really, really into it and gets a little worn out and heated up so he sweats.
In any case, it is nothing to worry about. It just means that he is a)probably nervous b)into it and c)very hot

It doesn't really mean anything if making out is all you did. It's just coincidence.

a sweaty nose is nothing to worry about, it just means the pores on your nose are clean so it allows sweat to pass through. people who dont sweat on their noses have clogged pores. Or It means your are mean
a sweat shirt
Just means he can be turned-on quite easily, and defiantly wants you.
Sweat: means soldering.

By stale sweat I'm assuming you mean sweat that has dried? First off, there are lots of electrolytes that you lose through your sweat. Secondly, bacteria like to grow in moist areas and sweat is very moist as you well know. When bacteria get in the sweat, they use it as a food because you have all these nutrients you lose and when they use the sweat as food, they release a gas and this is what gives it that smell. The smell will stay even after it is dry because it has not been washed away.
You mean sweat glands? If so then sudoriferous glands.
