I have a partner with whom I have an agreement to disclose in advance the desire/intention to have sex with a new person. We've used at least three definitions of "sex" over the course of the past three years. I mention this as a way of saying that there are many different ideas of where a "starting point" starts.

As long as you're willing to wait on going forward until you're ready to talk about it, I think that's healthy. Ultimately, when you get ready to talk about it, hash all of that stuff out- does he want you to tell him whenever you have a crush or think someone is hot? Does he want you to tell him before you approach anyone or start anything, etc.? Make sure, when you're ready to talk about it, that you're both on the same page.
