I am 19 years old, male, student. Last year 2017 around august I had once unprotected sex with a guy. After new year I noticed like a change of look of my anus, reading on forums I discovered it could be hemorrhoids or anal cancer if I caught hpv virus, could cancer develop so quickly in less than 6 months if I got that hpv virus or I got something else I also had 2 look alike genital warts but got them 5 months after sex. And the disappeared if I can i?ll send a photo so You can take a look at it. My anus from the sides got blue marks like its some kind of veins got bigger but reading on internet it could be hemoriods od anal cancer i? not sure. Please can I get more detailed answer i?m so worried I can?t go to hospital because all my family works there. Regradlesly Adam.
