VAGINA RIPPING ?! During birth!

Okay I'm seriously really concerned about this, this is literelly the only
Thing I'm scared about besides csection ! I know that some woman need stitches after because they have ripped giving birth! I'm very small down there & don't have very stretchy skin like anywhere so I'm super scared I'm going to rip! I know you stretch out ! But iv been told
Of people ripping down to them bum holes ! & im freaking out! Has anyone ever ripped before ? Or how bad? & what was it like to heal after? Is there a way to make it not happen?! Lol.. I imagine stiches there after birth would make everything harder more stressful ? 😕
