Pain during sex

Natalia • Being a mom is what I was made to do ❤️
Hello, 
So my husband and I have noticed most of the time when we have sex I have a ton of pain to where we or more me can't enjoy it and I end up in tears. I have been to gyno and my family med doctor and a pelvic pain doc multiple times and they say everything looks okay my muscles just spasm on their own. But when having sex I feel like I have a floor burn up there and it's unbearable most of the time but it's only on the front inside of the vagina not the bottom wall. We use lube and everything which sometimes helps. It's also the same thing when I use a tampon during my period. Hurts to have one in, put one in, or taking it out. Anyone else have this happen? I know this is a lot to talk about but I have no idea what to do.... And it's hard on our relationship 😞😢 any suggestions help.
