Young and nervous

So I’m 16 currently and have been dating this guy for 6 months and I know he’s keen to have sex but he says he would never ever pressure me into it and is happy to wait as long as possible. And I want to have sex too but I’m nervous that it will be really painful. Because I can get a tampon in fine but I have tried fingering and I could only get one finger up there and it didn’t feel good at all and I’ve seen his dick and it’s a normal size but I’m scared that it is gonna hurt a lot and I cannot tell if my hymen has broken yet so I just don’t know lol I need advice. Also how can i tell if I’m wet? Because I get turned on by him a lot but I just am not sure if I’m wet or not?
