Well, he'll be very hopeful, I can tell you that straight off. Dinner at a gal's place is very special indeed. The ritual of sharing food is old, probably older than civilisation, as it is so deeply ingrained into us. It is a code for "I am very interested."
So yes, he'll expect at least a very hot make-out session during the movie, and probably angle for more. All the guys I know would assume the invitation was for more than food, especially after you have been seeing each other for a while. I certainly would. Part of you is very interested, or you'd not be inviting him. Part of you is, to be honest, scared.
But, you know what? This is entirely up to you. I say this and say this, until my fingers can type it without me even thinking about it:
If you feel uncomfortable with doing something, then don't do it.
Your body. Your choice. No one else's. You owe no one anything at all. Yourself freely given, or withheld, it is your right and your decision. If you are not ready to sleep with him, don't, though if he, or you, intend to sleep at all the first time, you are both total amateurs.
Always, your eyes should be open. You were smart, you asked. Now you know what he'll be thinking. And can decide according to your needs.
looove this.
