I know you asked only for guys' opinions, I'm a woman, but I'm going ahead and answering anyway:
If I were you I would approach this carefully, not with heart in full flower. Do you want a guy to know you and how much of that can you stand? How much of your life are you willing to share? (dreams, family, bodily functions, sexual history, perverted relatives, daydreams, fantasies, etc.). If you keep secrets, could you stand to tell them to him? Can you trust him to keep your secrets or would you want him to share? A choice for secrecy or for openness determines the direction your relationship goes. And the choice isn't an absolute either: you can hold things back. The more secrets the more personal individual space you have in a sense, but the more solitary, too. Do you know what I mean?
