My boyfriend and I have been dating for 2 years now. For the majority of our relationship, our sex life has been completely normal. But about half a year ago, it started to hurt when we would have sex. I went to the doctor and she tested for any STDs and infections, but everything came up negative. As sex is now painful for me, I can't seem to get in the mood anymore for anything. Absolutely nothing seems to get me aroused, even if we do things I know won't be painful for me. I don't know what to do to fix this...

Has anyone else ever experienced this or have any advice? Any help would be appreciated!
