Does this look like Herpes or something else?

I just noticed this today. It doesnt itch or burn when I pee at all. I NEVER wear underwear and been wearing tight polyster pants all day. I had sex the night before and when I have sex. I put a rough washcloth way in between my vagina because i hate being wet at times. i went to sleep like that and most the morning like that so idk if that has something to do with it being in moist and all. I just got blood tested for Herpes one week ago. I was just curious. Both negative. and I just had annual pap smear as while. she said i was JUST starting a yeast infection and gave me medicine. ill be going to the doctor tomorrow
