unsafe sex burns

Sooo.. I decided to go home with this man who is known as "no foreplay" and I believe it now. I was not very wet as usually so It began to get painful I told I decided to stop it because I couldn't continue. Next day I had sex again and I could feel that it still hurt some. Next day I decided it wasn't a big deal and the friction hurt. Luckily I was very moist the 3rd day. Now it's been 5 days since I went home with mr no foreplay and it burns when I wipe myself and I also have my period. So you go figure my discomfort. I applied coconut oil and arnica potion to see if it helps. It hurts in my lower vulva opening. Any ideas? There's no odor or abnormal discharge. Just burning sensation when skin is stretched.
