His rod is too BIG!

So my new boyfriend had this idea for a dinner date and a movie. Afterwards, we went to my house while no one was home. Things got freaky and after he went down on me, he just jammed it in and I swear it tore my vag. It hurt so bad but all I could do was moan because it was turning out to be the best sex I've ever had. My vag hurts and it's been over three days, what do I do?
