girls i need help😖

I haven't had sex for while now like a couple of months not because I don't want to but because my bf is always busy and so am I ... well today we decided to have sex ...but OMG it felt like it was my first time having sex again it hurt like soo much😥 I told him to please go slow because it hurt and so he did and then he try to go a lil faster and I was trying to enjoy it but it still hurt ..by the way I was really wet down there so I dont think it had to do with me not being wet enough anyways he try to go deeper but I stopped him because I was in so much pain ..I don't know what's going on I use to enjoy sex?
