Broken

I am a 23-year-old female, sexually active for seven years, and I can’t reach climax. I am extremely frustrated. I have a wonderfully patient and helpful partner. He has tried hard to no avail. I can’t even get myself there. I feel like I am broken. My partner and I talk out anything that is bothering me, we try different things, but no matter what the situation, I can never reach orgasm. When I went off birth control, I brought up to my doctor that I had never had an orgasm, and she told me that female orgasms are largely a mental thing. She suggested I try using fantasy, which was not new to me.
Other than this, my partner and I have a healthy sex life. I don’t know what to do from here. I start to wonder if there is something wrong with me.
