I hear you on the bladder and bowel issues! I've had them since my hysterectomy too. I don't have painful sex but I have no libido so no sex happening. I would think that ovarian cysts could exacerbate bladder and bowel issues. Not sure about painful sex. If you've had that since your hysterectomy, then cysts are not likely the cause. That would be more apt to be a vaginal cuff problem, a too short vagina, vaginal atrophy, or endometriosis (if you have that). Hopefully, the cysts will resolve and associated symptoms improve.
Having had my life upended by the removal of my ovaries (and uterus) and now aware of all the increased health risks and loss of quality of life, I would advise against having your ovaries removed. Studies have shown the importance of both ovaries our whole lives despite the high rate of oophorectomies. I'd be happy to share details if you'd like.
