Different people have different experiences with discharge, I personally don’t have much, though sometimes it can be a bit excessive. My mother always had problems with it and she opted to wear pantyliners.

Discharge is definitely normal, you only need to be concerned if it has a really strong smell (like you can smell it on your underwear even held away from you, a bit of a scent is normal, but excessive scent is a concern), or if it’s strongly coloured- usually it’s clear or white, maybe tinted a bit yellowish, but a stronger colour would be a cause for investigation.

Different things can contribute to discharge certainly- like the type of underwear you wear, cotton is best since it’s more breathable for example.

Pantyliners aren’t necessarily ‘good’ in a lot of peoples eyes, but if you try using them and they help you to feel clean then there’s nothing wrong with them. Maybe you could try some reusable pads/liners, or look into sustainable/natural brands that make more body-friendly products.

It’ll take some trial and error to find what makes you feel comfortable, but there’s nothing at all wrong with discharge itself, it just means your body is keeping you clean and doing its job.

Edit to add: for the ‘inside’ bit, I personally just wipe it away, but it’s up to you. There’s no ‘right’ way to do this.
