Newlywed's right, just tell him honestly, the way you've told us. He needs to respect your right to say "no." And (unlike my situation), because you say "yes" sometimes, it should be easy for him to respect that.

Tell him, "sometimes, I just want to cuddle without sex. I want you to respect that."

Tell him, "I like to flirt with you, but let's enjoy the flirting without you thinking that you have to act on it immediately."

It should rarely be "all or nothing." You know what they say, "everything in moderation, including moderation" Go wild sometime. Go for a simple touch sometime. Just sit in the same room and read sometime. Do him doggy style in the woods sometime. You know what I mean?
