bump near my erm…regions after accidentally popping it. what do i do???

i had this bump around the place where my genitals and thigh meets, i noticed that bump would leak a clumpy dough white substance which i tried to brush off, but eventually after sitting in a certain position, i felt it pop. i then noticed after that, it left a small, red, flabby piece of skin which seems to be sort of ripped out of my own? its been an entire week, nothing changed. it doesn’t even hurt just feels a little irritating when i sit in a certain positions i guess. no i haven’t done anything either so i know it isnt any sort of disease, im just so confused on what this is and im asking on reddit as this is really embarrassing to talk about. WHAT DO I DOOOO IM GENUINELY TERRIFED
