I think this may be a damaged spot in your relationship - you've forgiven, & begun the healing - but nobody's gonna forget...a comparison might be made in that there are may of us pervs here who enjoy a little "non-consensual" fantasy now & then, but to anyone who had endured the real life brutality of rape, that may never be a game they could enjoy...could be your wife is afraid of ever going anywhere near that pain again, even in her deepest fantasies...
just my 2 cents...
