He gave me his number, now what?

So there's this guy that I'm really attracted to and we've been talking ever since I added him to Facebook. He gave me his number and told me to call him if I decide to go out tonight. He encouraged me to go out.

Should I? I mean I really like him but I don't want him to think I'm easy.

I feel like if I contact him while we're both out and partying it'll turn into, just a really hot hook up. But I might want something more with him (I don't know him well enough yet to know that though).

Should I play it off tonight and wait a weekend, see if he's still interested in me sober, tomorrow? Or should I just go for it?

If I don't call him from a party tonight, when should I use his number and how? (He doesn't have mine)
