Pain during sex? possibly TMI

Sorry if this is TMI, but I was wondering if any of yall are also experiencing painful sex. My vagina has been a lot tighter than normal, (due to the increased bloodflow I'm guessing?) to the point where my husband can't even fully get it in. Sorry again for yhe TMI, but I'm pretty desperate for advice here. If anyone is experiencing something similar, or has remedies, please let me know. Thank you mamas.
