Sex with boyfriend hurts

Here my story , I've been trying to have sex with my boyfriend. But everytime we try it hurts, a lot. He tells me that I have to open my legs as wide as I can and he just has to push it in and get over it. That dindt work , he started sticking his finger hard inside me without any warming up and it hurt alot he said he needed to open me so I get nervous and want to stop he gets really angry and starts screaming( this just to happen the first times of trying it doesn't happen that often anymore but he looses his patiance and hard on) what should I do? Is it normal that it hurts so much?
