Raw down south??

So I don't have the courage to post q image and I'm honestly sure no one wants to see my vag lol but I had my son 18 months ago ... Long story short I've had issues being super super dry down there ever since .

I never had an issue before him seriously like I would flood my own underwear at the thought of getting down with my hubby and other times I had some sort of cm that kept her moist, but now it's like what is wrong with me ??

I hate having to look at my husband and shave my head no and have to go get the dresses tube of lube , we both hate the feel of it. He's acting strange like trying to get me caught up in cheating or something every time I turn around its what did you delete what was you doing?

When I haven't done anything , it breaks my heart and the only reason I can think he's acting this way is cause I can not get wet! I.e. Seen many doctors cause literally it's like I have no CM what so ever .. And no one has a answer they just look at me and say use lube .

Now it's been so long that I'm literally raw down there not from sex but cause i stay soo dry it's like when I walk it's rubbing and making me raw ... It's swollen and soo very uncomfortable. Has anyone done this ad what was the cause ???
