At the top my clit is pink but as you go down it starts to turn a dark dark purplish

Hi! Umm...well I have been very insecure lately with my vagina. My clit is just weird. At the top it's pink but as you go down it starts to turn a dark dark purplish kind of color and it looks stretched out. I've never had sex with a man. I do masterbate, though..should I be worried
