Helppppp 😭😭😭 painful sex

So before I was married I used to have like a lot of sex and it never hurt.

Now that I’m married to my husband I find sex to be kinda painful. Not once he’s inside of me but like as he’s putting it in if that makes sense. Once it’s in it feels great. It’s just getting it in. We also use lube because I tend to be dry. He is on the bigger side, but is this normal?? Has anyone experienced this? What can I do to make it less painful? I love my husband and I feel like I’m turning him down all the time because I don’t want it to hurt. 😔😭
