Personally, I wouldn't be comfortable keeping those things to myself.
I would be very unhappy if my husband was keeping similar things from me and I don't see how wanting complete honesty from your partner is wanting to own them. I'm a huge believer in radical honesty in committed relationships.
I think its great that you've taken the steps to discuss with him as much as you have but you say yourself that one of your reasons for not telling more is that you want to continue to see him. Thats taking a choice away from your husband. Thinking you've made something obvious doesn't mean he really knows.
