Each and every woman is different in her healing and journey through hysterectomy. Yes, there are similarities and why we can talk to one another about our experiences and offer advice.
If you haven't already sought a 2nd or 3rd opinion you may want to do that. Also make sure if you have concerns that you consider the less irreversible options first. I know you stopped a UAE before but you may want to revisit that procedure. You can always step up to a hysterectomy but you can't step back from it and you have to be absolutely sure that this and it's consequences are something you are ready for if you are having this for non-life threatening conditions. There are members who didn't have a choice because of cancer but in all other situations this is considered elective and you have to be comfortable with it.
Speaking from experience there can be sexual dysfunction after the surgery and it can be difficult to find a doctor who will help you with it. If you are concerned talk to your doctor now and say "what will be your recommendations and course of treatment if this happens to me".
In my personal experience and from reading here the following are some things that can influence the possibility of dysfunction....
Did you have pain prior to the surgery that interfered with sex? Many members find that the hysterectomy removed those issues and now sex is better (remember I said many, not all).
Did you keep your ovaries? If you don't keep your ovaries you will experience surgical menopause and that can be rough.
Did you already go through menopause? If so you may have already experienced some of the libido and lubrication slow down but even at that the ovaries produce some hormones so if they are removed things may change.
If you kept your ovaries did they go to sleep? The blood flow to the ovaries is interrupted in surgery and it may take awhile for them to wake up and in some cases they don't wake up, so you are back to menopause.
Trying to go back to normal activities to soon? When you resume intercourse go slowly and not as vigorusly as before until you know you are healed. It takes months to fully recover. If you go in tense you can trigger musles that cause sex to be painful, this can cause it's own set of issues.
Expect things to be different after the surgery. If they are you aren't negatively surprise and if they aren't you are happy and relieved.
You have to be ready for the outcomes because as UK Lady said there is adjustments with having a hysterectomy.
