Is this okay?

Am

I am single, have gone out with a guy twice and we talk everyday, but have never discussed our "relationship" to one another. Meanwhile, I occasionally would talk to another guy, who has now asked me out, but I've never done this "dating two guys at once" thing, even though technically I'm not really evolved with either (yet). Is it okay for me to go out with this other guy? Should I feel guilty by doing it?
