Perhaps see a sex therapist together if there's one in your area. Sounds like you both have been through some tramatic stuff, but that doesn't mean sex has to be over with or trouble. Sex starts in the brain first. Second of all, orgasms with only vibrators are completely normal for many women. You are not broken! Vibrators are great tools with operators that know how to use them. Keep it up, and enjoy your sexuality! Above all it's yours whether your partner can fully participate in it or not.
