Position help for a big 🍆?

Okay so I know this is a little awkward but I have asked all my friends for advice and they don’t really have any so I’ve come to the ladies of eve for help 😭. So I’ve recently started seeing this guy and he is amazing but he is very well endowed (length more than width) which I never imagined would be an issue, but when we did it for the first time I literally could feel him hitting my cervix and it was quite painful if I’m being honest. We tried me on top which was very quickly ruled out as an option, then prone bone (me on my stomach and him laying above me) and this was better but still quite uncomfortable. I don’t want to call it off because of this because he’s genuinely so nice (and yes he was very respectful about it all and reminded me constantly that we could stop and was as gentle as humanly possible) but I don’t know how on earth we can get around this so I’m not in pain. Do yall have any positions or advice that could help?
