White Wart On Outer Lip Could This Just Be A Zit Or Something More Serious, Like An STD?

Could this just be a zit or something more serious, like an STD? - white wart on outer lip

Bumb Recently I have noticed a white view of the outer labia. I went to the doctor and he said it was not herpes, and certainly not looking like a wart, only an ingrown hair or maybe a gland or something Swallen. But to be sure to put acid in the computer and left. He turned, however, and now there are 3 of them. I want a new appointment, but I'm very nervous. Is there an explanation of what might be? Could be more than an STD? My ex cheated, then it can not paranoid.
