I'm female, so can't really help. What the male fm's have already said is probably more likely because they're gonna know how men think better then me.
To me it sounds like he really does see you as just a friend though (I don't think men are like us - they say what they mean, don't they?

whereas we hint, say the opposite, just adapt the rules whenever we feel like it, or completely change them when we feel like men are getting close to understanding us).
Like Mr M said, he could be talking to you like that purely because he feels comfortable with you as a mate - nothing more.
He could however just want a quickie and he's testing the water to see if you're up for it.

(stressing he only sees you as a mate so you don't get the wrong idea if anything like that does happen). Either way, it doesn't sound like he's looking for a relationship.
