Why does sex for me hurt when I first start in the beginning?

When me and my boyfriend have sex its good don't get me wrong

but in the beginning when he's pressing it in it hurts %26amp; it kinda burns.

It feels like that for about 5 to 7 seconds then after that I start feeling pleasure.

But does anyone know why it hurts in the beginning?
