Is this a std?

ive had this for a couple mouths should i be worried about it being a std? every once in a while ill get a sore or too but its normally around my period so i just chalked it up to my pads irritating me should i be concerned is this normal?

doesnt look like one. if it was an std you would have other symptoms such as discharge and itchiness. get it seen by a doctor as it might just be a skin condition

thank you so much
