What to do about bleeding nose and gums?

I just came here this fall. Since then, my nose has been bleeding occasionally without any injury. My friend told me it was because of the dry air of U.S. Is he right? How can I prevent this situation? I also have a problem when I brush my teeth. My gums are always bleeding and not just a little!! What should I do? Thanks.


Can I start a polyamorous relationship with a man and a woman?

I'm a bisexual female and I've been dating a girl on and off for the past couple years. "On and off" due to distance, but the point is that as much as I love her, I still feel like there is a male void in my life. I'm not sure if it's because I get a lot of attention from guys and very little from girls, but lately I've been thinking that I would feel most comfortable in a committed relationship with a man and a woman. Do you think there's any hope in finding others who would be able to maintain this kind of relationship in a healthy manner? I have a lot of difficulty finding the right chemistry with people to begin with...


How can I move forward with a homophobic roommate?

I'm a lesbian and I think that my roommate could be slightly homophobic. We have never really had a great relationship but now that I've come out to her, we don't talk much at all. How do I talk with her about this issue so that we can put it behind is without making it so awkward?
