hmm , i think its gonna help u if u do share it with someone, it doesnt have to be him if you cant see yourself telling him.
My concern for what u want is that it may not solve the problem for you, it seems like a denial of self (sorry only my thoughts not wanting to push them on you) . Its such a big issue i dont want to blunder in and cause u any harm here. Thats why i think that a understanding professional will be able to guide you best. But i am glad your expressing it.
