Virginity help

Na

I lost my virginity to my boyfriend on the weekend and he’s quite big down there. However I don’t know if he tore me or if I have something wrong with me. He’s had quite a few sexual partners and he gets tested after every two people but I don’t know if I got something. When I urinate it burns and it’s uncomfortable. But I only got this pain today but I lost my virginity on Saturday. Is this normal?
