This is hard one, on the one hand telling straight away can scare people off. However on the other hand, if you leave it too long and then tell him, you're gonna risk breaking up anyway, as you haven't been honest.
I have always told straight away, and anyone that bit more serious, have asked questions, looked up CF, got scared, asked more questions-then they've been ok with it. My friend has always had a harder time, though he's getting there now.
I think it is totally dependant on the guy you like really. A whole lot of everything is going to depend on how he feels about it all. If he does lose interest though, I'd say it's better you know early on before there are any really strong feelings. Think about how you will describe CF. I always start with it's a bit like asthma, and then add the worser stuff later.
Hope this helps, and hope it all goes well
All the best
