help please i have no idea what is wrong down there

i think i may have gotten a wax burn but i am not sure. its has been very itchy and im not sure if it could possibly even be an std. i am going to get tested soon but i hope someone here can help me too even if it is just on how to heal the skin please!

Did you try any new products – soaps?

update i got it all figured out. std tests came back negative and the nurse told me it was just regular chaffing. ive been using vaseline on the outer parts and its 100x better now.
