I’ve had these patches for years… what is it?

hey everyone! I've done STD and STI test in the past its always negative. But i have had these patches for more than 2 years now.. sometimes they itch but they just look very bad i am very shy to be sexually active i am very insecure about my vagina and this makes it worst :( can anyone tell me if they have had this? or what it is? and what can i do? could it be psoriasis?

It doesn’t look like psoriasis, but you need to check to see what it is.
