Can You Line Your Waterline Whilst Wearing Contacts?

Im 17 so understandably have an affliction for eyeliner,
I also have astigmatism, which means I see straight lines blurred,
I feel very self conscious when wearing my glasses,
So i’ve decided to get contacts.
But are you able to line your waterline whilst wearing contact lenses?
Or will it stain or damage the Lens?

Line On Toric (astigmatism-correcting) Contact Lenses?

I noticed a radial line on my toric (astigmatism-correcting) contact lenses, Acuvue Oasys for Astigmatism. Is this line supposed to be pointing superiorly if the lenses are placed correctly? Or is it supposed to be pointing laterally / medially / inferiorly, or is the direction of the line not related to the correct placement?
