I'm a happily married fat woman and I'll never understand why my sex drive tanked

So. I'm a fat girl, 29f. I'm 5'3 and 320lbs, and I have been married to my husband for 4 years. We have 3 kids together, from 2-6. I am exclusively a stay at home mom.<br><br>When my husband and I first started dating, we were all over each other and eager for any time we could be alone. I was always a "plus-sized" girl, but I used to run a lot and was more toned. Weight gain happened more recently. <br><br>22 months ago, I had my third kid. I had what my doctor described as a "traumatic birth", which he said was why we were having weirdest of issues with my bladder (peeing in my sleep, during the day, constant pain and irritation, etc.) After a ton of testing, it was confirmed that my entire bladder muscle is basically destroyed. I will now be having surgery to fix that. <br><br>While I've had this whole thing going on, I have also had pain in my vagina. Very painful burning, along with itching in my entire pelvic area. I had an appointment with my gynecologist, and she said there was a polyp (which I was able to feel) that was the cause of the pain. She took care of it right then and there, but she said she gives me a follow up appointment in a month and then performs a pap smear to check for any abnormalities. I recently went back and everything looked fine, except she said the polyp had a weird cellular structure. She seemed to think I should go to the ER and have them test it again. So I did, and they gave me an appointment to see a specialist next month. <br><br>I had my husband pick up my test results so I wouldn't see them before I go to see the specialist. <br><br>All that said, one of the side effects I discovered from this polyp was excruciating pain during sex. I was terrified to say anything to my husband, but I did. I explained everything and the fact that I was seeing a specialist. I wanted to work on sex, but we both didn't want to hurt me so we just kind of dropped it. <br><br>But my sex drive tanked. I went from always thinking about it and being turned on by my husband to not even thinking about sex once a day. It's like one day I woke up, and then the next I was over. I am not attracted to my husband, I don't even think about it. It's like a part of me just turned off. It's so weird.
