HPV Genital Warts on Anal Opening?

[nasdf]

To preface all this, my ex-girlfriend called me a few weeks after we broke up and told me she had HPV and abnormal cells.  They did a biopsy and determined that they were non-cancerous.  This was about 6 weeks ago.

Yesterday discovered a small bump on my anus.  It's hard to see obviously, but from what I can see in the mirror there's a pimple-sized bump that is dark.  It's hidden when my cheeks are closed but it's about half an inch from the opening.  

There is only one, so I'm hoping it's not genital warts?  I'm not sure when it showed up but I'm pretty sure it wasn't there 2 days ago.  Also, is it possible to have genital warts on the anus but not on the genitals?  I have never had anal sex or anything, just vaginal and oral sex.  

I haven't had blood or puss or any of the things online that seem to be associated with hemorrhoids or a cyst, but there's so much conflicting information it's hard to tell what's accurate.  I'm only 24 and in general good health so I'm hoping that this is nothing but at 25 my Dad had testicular cancer so I'm extremely paranoid about something similar happening to me.  

Could this be genital warts? Cancer? Just something normal that will go away?  I would really appreciate any info you have to offer.

Thank you

You would honestly have to have a doctor look at it for a proper diagnosis, this could be a wart or a mole... we can't tell you for sure. BUT yes you can have anal warts with out having anal sex. and Yes you can have it there and not on your genitals. My best suggestion would to see a doctor and have the bump biopsied for a proper diagnosis.
