I hear you, about fear of losing the ability to have an orgasm! 55, 38, 20, even 80, geesh!!
I had an ovarian cancer scare, back at the end of June. I had, an u/s, as part of the routine for me, since I am high risk, due to my mom, dying from ovarian cancer. I had an egg caught ovulating on the u/s, and the doctor was concerned due to family history and I was braced to have a hyst with ovary removal.
Sorry, to read, you need a uterine biopsy.

Hope your husband can be there, for you, to hold your hand. Were you advised, to take Tylenol or Motrin, or some OTC pain reliever at least 30 minutes prior??
What other symptoms, are you displaying, to raise concern about ovarian cancer? Have you had the CA-125 blood draw? That would show elevated levels, that would determine, if you have an ovarian cancerous inflammation.
