I have so many questions.

So I have sex last night twice in a row and then again a few hours later in the morning.. after the second time I was bleeding? I’m 24, not a Virgin at all, no kids.

My Vagina is suuuper swollen and sore today. I looked inside at the vaginal opening and it looks like weird larger bumps of tissue blocking my opening?! What is that?! Someone HELP me.
