Sore on vagina, what is it?

i noticed a sore on my vagina but theres no itchiness etc but it has almost a throbbing kind of sensation to it and im scared over what it could be?imageimageimage

it mabe from shaving but it may also be herpes u should go have it swabbed to be on the safe side

My first guess would be a small shaving cut that has become infected. Apply antiseptic and see if it goes away. My ex had Perianal abcess that looked similar and was also painful. See a doctor if it doesnt clear up soon.
