Painful sex and blood

Jess

So we were having sex and it was going great and I told him ‘harder’ to which he changed up the position and started going so much harder. I felt a sudden sharp pain and then it constantly hurt after that and got so much I had to get off him and we had to stop which I felt so bad about. And then I noticed blood on my leg and on the bed, he saw it too and was like wtf. So then he looked at the condom which was covered in blood too. He then put a finger up me, to have a feel about, and told me that it felt different then normal.

What happened?!

Please help xx
