Friction burn?

Okay so on Valentine’s Day, my boyfriend and I tried having normal sex like we usually do. But it started to hurt a little... so we stopped and waited till the weekend. But then it got worse. It doesn’t hurt to pee or to walk or anything. It just hurts after sex and during. But the pain goes away. On the picture I circled the hurting area, but when I took a mirror and check down there it had a tiny tiny tiny little tear I drew a line on the picture where the tear was. Is this from just being dry and getting friction burn? Help me 😩I’m at my wits end. I know it’s not an std tho.
