Burning feeling?

elly

My boyfriend spent the weekend with me, he slept over Friday night and of course we had sex. we had sex again today, it was amazing! He went harder and deeper then usual but once he pulled out, i noticed my vagina was burning. It hurt so bad I couldn't even walk. He took me into the bathtub and i sat in hot water which helped but im worried the burning feeling is something to be concerned about?
