he cut my vigina

So yesterday I was chilling with this guy that I've been talking to for a few months, and he kissed me and we made out for a bit, he started sucking in my nipples and the next thing I knew, all my clothes were off. So anyways, he put his hand down my pants and I put my hand gently on his wrist and was going to tell him to stop (because I didn't want him to think he could get in my pants that easily) but I wanted it so bad and his hand was already half way in my pants so I'm like fuck it. he rubbed me for a while and then he pushed his fingers in my pussy with a gentle but forceful push (idk if that makes sense but lol). Anyways, long story short, after like 30 mins of finger fucking I went home. when he texted me after he got home, he said that there was blood all over his hands. so I looked in my pants and it was almost like I got my period. I washed my panties and they were FULL of blood.. And when I pee it hurts sooo bad :( is there any way of easing this pain? should I seek help? It's only been a day :/ it's sooooo painful guys.
