the wrong hole

My boyfriend and I were having sex last night the 31st.... we both had gone out that night and were pretty drunk. I was on my stomach and he was on top from behind when he "accidentally" stuck it in the wrong hole. I immediately freaked out and started crying because it HURT like say worse than losing my virginity hurt...... I cried for a while until we went to sleep. I woke up around 3 am and went to the bathroom and realized I was BLEEDING and I am still bleeding and I'm excruciating pain. Is there anything that can help the pain? Has this happened to anyone else?
