So, my boyfriend's ex is a stripper.  She's also one of those nude models, the kind where they are naked and sticking fingers up their vajayjay.  I also know that that photogrpaher (sounds like Piecket) takes pictues of strippers and if they aren't that pretty, he will have them blow him so at least they will get their face on his site.

What I have an issue with is the fact that she has genital herpes and lied to my boyfriend dueing the whole time she was hanging out/ dating him.  He found her medication and she said that it was an anxiety medication.  So, now I am fearful of contracting genital herpes.  

I decided to announce it publically.  And now her older sister is attacking me.  What thell?
