To be friends or not to be friends first?

I always hear that when you are attracted to, to not become friends or else your stuck in the friend zone (which I kind of found to be true). Then again on the other side of the fence there are people saying become friends first then try to move it past that. There are a separate set of people that say get laid first then become friends and if it doesn't work just keep move it. I know girls tend to say become friends first, but then they don't really act that way. So I want the truth about this topic?
