Labug, I am like you, wanting to have things done a certain way and being the initiator of those things. I also like fun, spontaneous adventures! I like your idea of the alternating months to do something fun. Was that your idea or your H? For me the anticipation and mystery would be exciting. If it was me I would probably say something lighthearted like, "I've got something exciting planned for my month, I think you will really like it, just you wait!". (kind of hinting like, YOUR month is ALSO coming up, hint, hint!) Then just sit back and watch his reaction to gauge where he is at with the idea. If he seems to be flustered upon talking about it, or reacts negatively, then you will know you may have to back off a bit.
