My vigina feels tighter than normal

Sex with my man is mind blowing. We do it regularly and he always tells me how small and tight my vigina is, but last night we had sex and it took him long to get in and when he finally did, I left him with bruises. I also noticed when I was cleaning up my finger failed to go in, am I closing up?

Has anyone experienced this, please tell me this is not a healthy issue.
