How to know if your guy-friends have ulterior motives? (guys answer please)?

Anonymous
A lot of times they will do things like lend me their jackets, give me money, pay for my movie ticket (even though I insist I will), drive me places, pass me notes with test answers on them, etc...

I realize this is normal, friendly behavior and I shouldn't be paranoid about it. But I want to know if a guy does these things for a girl because he's being a good friend or because he has other reasons for being such a gentleman?

Guys, please answer!
