Don't be so obvious. You look like an idiot.

None of that "Make it last" stuff. It,s stupid. If you,re not dating the guy, then you need to be very careful in how much attention you give them. You want to hint to them that you,re interested, but don,t go overboard. It makes you look like a whore. Men want what they can,t have. If getting you looks like a challenge, they,re more likely to go for it. Take your time. Mystery is a good thing, just make sure you,re using it right. If you hang on your crush,say.. Linking arms with him constantly or something.. He will most likely find it highly annoying. Pay special attention to how long you,ve got linked arms, and also to how often.
