Everytime!!

Everytime I have sex, for a day or two afterward my vagina smells bad, not fishy or anything but just bad. And there's always these white chunks that come out and idk what they are!! If I touch it in the first day after sex then it gets kinda itchy. It's usually super dry even if I masturbate and orgasm, I can't get a finger in. Does anyone know what this is??
