i'm not sure when it started to appear but i only noticed it last week. it's only rough to touch
up
Do you have any other symptoms?
like itching, burning, vaginal discharge that is different than your normal and usual discharge?
nope, no other symptoms 
I suggest you getting it checked out by a doctor to rule out the possibility of having any STD, since it has clinical signs of warts
ok thank you for the advice! just curious, do you know if warts can go away on its own
sometimes they can, but the doctor can prescribe medication to help get rid of them. however genital warts are likely due to HPV, which is a virus, meaning warts can come back. HPV is common and theres no cure but they say that your body can fight off the virus within 6 months- 2 years if you have a healthy immune system! try not to touch the area so it doesnt spread and get it checked out soon. The antibiotic creams are most helpful when the warts are smaller, otherwise other treatment options can be surgical. I am having a scare myself too and I will be going in next tuesday for a biopsy to confirm if i have warts. Good luck!
warts may may be an option but in the photo it looks bruised and is cracking so maybe its something else! warts are usually flesh colored or whiteish. keep us updated on what you find out!
