Vaginas and sex post partum

Just wondering if sex is still painful or uncomfortable for anyone. I'm 5 months post partum and it still hurts a little especially at first. I had a second degree tear (stitches) but an easy recovery.

Also. My vagina seems to have like "ridges" going lengthwise inside. Well I only can see at the opening that's what it looks like. I have no other way to describe it other than my actual vagina (inside) surface isn't smooth ? Maybe from being stretched and now it's shrunk back down but still has some extra baggage to it? lol I feel like I can just see it at the opening that there's bumps/ridges. Anyone else have any changes to theirs?

And on a final tmi note, my vagina odor has changed. Don't have an infection. Just something ive noticed since giving birth.
