Hi Suzzane,
For guys, it is almost impossible to forget what my gf or now wife had done (lost virginity) before marrying me. (based on my own experiences!)
It is better not to tell all about your past, if you feel it will hurt and damage your relationship with him.
Since he already knew about your past, that it is up to him to "recover and heal" his mind.
No matter what you do or want to do for him, it will not change what he can do for himself first.
He must let go his "own" feeling first or else there will not be a happy marriage later on. Both will suffers!
If he really love you, he should let it past. (almost impossible)
Sorry to say this, maybe he still "searching" for his gf or life partner and you are just "occupying" at the moment.
