It just occured to me while reading this for the first time (sorry, I've been married forever so didn't think I could contribute) that your boyfriend may have some issues with positions during intercourse. Since you two are so new, it may be hard for him to bring up. You may want to ask him if there are ways that are more "comfortable" for him.
Also, it sounds like you both are having trouble communicating. He's not telling and you're not asking ;0)
If you want to know what to cook for him, ask him. Everyone responds differently, and he may have some definite no-nos.
I think it's wonderful that you're here looking for information, but when it comes to the individual, there's no substitute for one on one communication of likes and dislikes.
I think if you start asking more pointed questions, he may just start
opening up. It's hard to know how much to tell a person when you're new to them, you never know how much they want to hear, he may be waiting for his cue from you.
