What is this?

This bump appeared yesterday. It was small and wasnt painful it just itched. when i took a shower today i watched it with soap and water thinking that would help clean it but since ive done that it just stings to touch it now. and now when i go to the bathroom if urine gets on it i feel it sting. its not horrible and i dont feel it unless i touch it/get urine on it. it doesnt look like any herpes pictures ive seen but the stinging is herpes like so im worried. it doesnt look like its filled with liquid though its just red on the outside and white in the middle part. i do currently have a bladder infection and i read they can cause you to get vaginal boils but boils apparently have pus in them so idk what to think

i currently have something similar
