Why does hurt so much?

So i had what i believed was a yeast infection in July, about 3 months ago... and ever since then has never felt the same again.i used to have a nuvaring during this time, but it was irritating and not making my yeast infection go away so i switched to pills and ditched the ring hoping it would help me out a little bit. i went to the doctor and she told me there was nothing wrong with me at all. i dont see how this is possible because why would hurt for me? it never used to hurt... this is really frustrating for me and my boyfriend, i hate this! so i waited about 3 weeks and decided to go to a gynecologist since nothing was getting better. my gyn told me nothing was wrong either! he told me to take a break from and to used astro glide lubricant. but that doesnt seem the case! it hurts on my right side more than my left, and the pain is mostly where the opening of my is my boyfriend takes forever to ***, and it hurts me for about the first 5 minutes of , and then i just kind of get used to it and it doesnt hurt that much for the rest of the amount of time. i just want to enjoy the way i used to again, i dont think just taking a break is going to cut it. is it possible that both my doctor, and my gyn are mistaken? help!
