Loose and tight vaginas

How do I know if I’m tight? I’ve only had sex 2 times and when I look in the mirror the hole looks bigger then when I was a virgin. (Which is expected) everytime I try to look this up I get different answers. Does sex make u loose? What does a tight vagina look like? Does the tightness change over time? Lol I know this is crazy but I just can’t figure out the right answer!
