Hi,
Honestly, the only person who could diagnose what has caused the bump on your labia, would be a doctor. Keep in mind that not every bump or
lump (that appears on your
vulva) is caused by an STD/STI. Bumps and lumps can be caused by ingrown hairs, clogged glands, cysts, pimples, and so on ~ the best thing to do is to wait for the doctors exam and try not to focus on worrying about the bump...
