Painful intercourse

My husband and I have been married for 7 years. We have a 3 yr old and 6 month old so life is definitely crazy right now. When we first got together we had no problem having sex multiple times a day. Even if I wasn’t instantly lubricated it still didn’t hurt. A few years into the marriage sex started to become a tad painful after but it didn’t happen every time. Now two kids later it is painful- like a burning sensation right around the vulva area. I’ve been several times to the gyno and every time is different. Mistreated uti, estrogen cream and finally one doctor said it’s because I’m not lubricated and told me to try a certain lubrication. My mind wants to have sex but vagina says otherwise. It has definitely caused issues. My husband is so patient and says it’s not a big deal but it sure is to me. Has anyone experienced this type of issue? I feel very alone and thinking that I’ll never experience sexual pleasure again.
