Why dont you have a glass of wine and build trust only thing I can really say, what you may have to do is see a councillor about the rape because keeping those fears/memories inside can really dampen any sitiuation.
I could not orgasm due to a the similar sitiuation but I turned into an alcholic met a guy and he helped me build trust in people its kinda of a two way street he needs to undertsand, maybe not pressure you but you need to find what makes you tick...
If you have to, buy toys or have him touch you till something feels good, you may not feel comfortable but sex is meant to be enjoyed, another option is to wear a headband over your eyes and just think positive...
I know it sounds weird telling your man where to touch you but how do you build communciation between you and your partner if you cant tell him something that simple(yeah mayeb not so simple)
best of luck feel free to send me a pm
