Burning sensation when having sex. Idea.

I am unsure whether I have a tear in my vagina or if it's a STD. I had being diagnosed with Herpes (oral) April 2016 and was tested for everything and that's all I was positive for. I am dating the same guy who gave me that disease and I've being 100% loyal to him. After some online research I thought perhaps I have gential warts but in saying that, it means his cheated on me. I do not feel any pain when I urinate or just generally. It was approx 3 days ago that my vagina just felt strange while I was doing the general day to day basis stuff and that night my boyfriend wanted to have sex and I said no to it because of me feeling a bit odd down there. But lastnight we were going to have sex and I had to stop him but it was burning badly! He had a look inside my vagina and saw something and I had a look myself which I don't really know what it is, although I've taken photos and would to show you to see if you may have an idea.
