are these razor burns or something else?

a couple weeks ago i decided to shave my bit and vagina and as usual, i got razor burns. at first they weren’t too bad but as the days went on i noticed a burning feeling as i walked and today i decided to check it out and found this - these photos are so gross, i apologize. but are they razor burns and chafing or something else? and how to i cure it? i don’t own desitin and i think if i told my mum she’d probably freak out and take me to the gyno and i do not want that at all lol.
