My coworker

How do I get her to shut the fuck up seriously. She talks to her girlfriends all day about the guys she is fucking. First of all gross bc she told me she doesnt shave her legs, second of all she asked me if i had any condoms on me. We're at work, seriously. She talks more on the phone then anyone i've ever met. Not to mention she does it loudly. You can talk all you want but dont do it infront of me. I'm trying to get work done, at least look like im working. It gives me a headache. Seriously, she is gross!
