I am still bleeding from losing my virginity yesterday?

My boyfriend and I had sex for the first time yesterday. It was my first time but not his. He said it would be better to go real fast to get the pain over with so it was very sore at the time and I bled quite a lot. The thing is I am still in a lot of pain and still bleeding today? I took a bath because I read that it would be a good thing to do if you're sore from sex, and it relieved the pain for a while, but now there's still blood, and I feel scared about doing it again. He said he wants to have sex again tomorrow but I think I'm still going to be in pain and I guess it will hurt more the next time especially if he goes fast again. I really don't want to do it again but I don't think it should be hurting like this much still. What should I do? Thanks
