White blotches on genital? Cancerous?

hello, ive had HPV for bout a year. i am still unsure which kind ive had, i think i have had the highrisk kind. they show small tiny visible randomly on my genitals. sometimes they go away and they have been away for a while. but recently ive checked and seen there is 2 small white blotches down there. im not sure what it is. and i dont know what to do for treatments. does anyone have any suggestions? its kind of freaking me out... :S
