What the hell

I’ve noticed that if I’m not the best with keeping up with my vaginal health this white stuff starts to build up on my labia and surrounding areas around my vagina and I’m not sure if it’s a yeast infection or not because it doesn’t come out of my vagina it just builds up around it, its white coloured and has the texture of goat cheese, I do sometimes get itchy down there but I’m not sure if it’s because of me shaving my vaginal area. I’ve been really worried about this because the internet says nothing, I don’t have any STDs or infections , but I do have sex regularly, someone help? Does this happen to anyone else?
