skin that looked funny to me?

HI i went to the doctor to get a visual exam for my genitals a couple of weeks ago. I pointed out skin that looked funny to me. He looked at it and said it looked like normal skin and wasnt a wart. I couldnt point it out of my mind so i continued to pushing the skin up with my finger and stretching it out to get a better look. I also did a vinegar test quite a few times over those days and once when i was stretching the skin with my finger. It started burning and turned white. i freaked out cause i thought it was a wart. I went back to the doc for another examination. he looked at it and said it didnt look like a typical wart but said it could be but wasnt a hundred percent sure so he refered me to a dermatologist. Im still waiting to find out. ive been keeping a bandaid over it but it still is red and when in the shower it turns more grayish blue. Im just wondering if it could be one or not or if i cause the lesion with the vinegar cause ive read the vinegar turns any lesions white.
