pain during sex

Hi guys I just wanted some advice because I’ve gone to the doctor several times and I don’t know what to do anymore.

I’ve been tested for stis and stds and I came back with nothing several times. I’ve continued to have irritation in my vaginal area and it also hurts when I have sex. I’ve changed body wash products and even just started to use water but it still hurts when I have sex and I also have irritation and itchiness in the follicle area . Idk if you guys have every experienced anything like that before but any advice or suggestions would be really helpful
