So I'm new at the whole relationship thing. I have a general question. How do you talk to a guy about a serious subject that concerns the both of you without freaking him out?

For example, the guy I'm with now I spend a lot of time with, but we don't spend a lot of time alone together. We are at his house a lot and his family is there all the time. How do I tell him I want to spend more time alone with him? I guess the easy answer is to just tell him, but I can be kind of blunt and want to be tactful about it.

Another example, we're going to have to have something like "The Talk" soon since I'm getting anxious about how he feels about me. It's really starting to bug me. Any ideas about that one?
