stringalong Are you so sure that he's certain to respond to your desires poorly? I don't mean to dismiss your concern and apprehension, and I could be quite wrong as I don't know either of you. But, it sounds like you feel as though you are letting him down before you've even said a word to him.
I agree with Read more… BackRubsNBruises. If you think that he would have a difficult time accepting you showing somebody else affection, perhaps present it to him differently. What if, at first, you both experimented with an outsider together? I think many people are less inclined to feel insecure or jealous if they don't feel that there is a threat to their relationship. I'd like to think that the two of you could have an easier time having taken the first step together. 🙂

Perhaps opening by asking him if there’s anything new he wants to explore or any fantasies or anything he’s curious about. People change and grow. He might be more receptive than you expect.
But, be prepared for if he isn’t. What then? Make sure you have plans in place for all outcomes. I really hope it goes well though.
