How can I tell my nosy roommate to step off?

I'm a junior in college and I live in a suite with five other girls. We are all best friends, except for one girl. None of us like her because she says anything that pops into her head (she told one of my suitemates, who is battling an eating disorder, that she looked pregnant), and she is constantly trying to find out gossip about us. After a night of fun, she will come into all of our rooms, and pump us for info (she hasn't gone out with us yet this year). She thrives on knowing gossip about anyone and everyone. My question is: how can we tell her to mind her own business and shut her mouth? Also: how can we tell her that we don't want her to live with us next year? Thanks for your help!


Are there tests for herpes and genital warts?

I have recently gone to a Planned Parenthood STD Clinic. From what they told me, they tested for everything "curable" (i.e., they did not test for HIV, genital warts, or herpes). I know where to get tested for HIV, but my question is: are there tests for herpes and genital warts? What are the odds of someone having herpes or genital warts and being asymptomatic? I plan to use a condom during intercourse regardless, but must I do the same for oral sex as well? Is there any way of knowing for sure if someone is clean of STDs?
