My boyfriend and I finally had sex

Emma

So my boyfriend and I finally went all the way which was a huge step for both of us as we lost our virginity to each other. Now he wants to have sex all the time but I'm still kinda sore from it and it kimda hurts a little when he puts it in. Not enough to where I wanna stop but enough where I'm wondering if it's normal? I'm 18 and he's 17.
