What does a normal vagina look like

OK SO - hoping someone can enlighten me here. I should definitely know the anatomy of a vagina but I think we all have had moments where we wonder if we’re “normal”. Well - I’m having one of those moments today. I’ve always thought I had a “tight vagina” , being able to insert tampons took years of practice, loosing my virginity was sooo painful, sex still hurts even 10 years after losing my virginity. My question is: is all of this normal? If I look with a mirror, I can’t even see my vagina opening. It seems my urethra takes up the whole space. Ladies is this normal?! Should I be able to see the opening. Is it normal for sex to be uncomfortable especially in certain positions? (Yes I know for play helps and to make sure I’m extra wet and etc..i know this)

Feeling extra stupid writing this but I think I have a bladder infection which is bringing my attention to my vagina and causing anxiety that somethings not quite right :(
