1) I'm a young gay man, and I'm concerned about oral sex and HIV. What are the risks, statistically and in your opinion, of receiving oral sex without a condom? Also, and this will sound kind of funny, I have braces, so I'm assuming giving head is dangerous.

2) A couple of weeks ago, my girlfriend and I were having oral sex and... well, to make a long story short, my penis got "snagged" on her braces and I received a deep cut on the head. I put Neosporin on it every night for a week, but the cut doesn't seem to be healing very quickly. I don't want to go to Health Services because of the embarrassing nature of the problem.

Help me quickly, please, because it also is very painful to urinate, let alone have any sexual activity. I was also wondering if there was a risk in contracting any STDs from this occurrence. I would really appreciate any advice you can give me.

1) You know when you get a cold and you have to blow your nose a lot and it gets all sore from rubbing it over and over again with a Kleenex? Do you know of any kind of cream or something that you can put on your nose to help soothe the soreness caused by frequent nose blowing? Any suggestions would be greatly appreciated.

2) I am a 16 year old girl who isn't very good at blowing her nose. I can blow the air down hard enough, but nobody has ever taught me a good technique for a proper clear-out. What is the best way to hold your nose in the tissue to get a really good nose-blow? How would you recommend I try to blow my nose?

What natural food or herb can help soothe stomach ulcers?

How can having multiple sex partners be a risk factor for cervical cancer? What is the difference between having sex with one man one thousand times and sex with one thousand men (not that I'm planning to!) one time?

I just found out that a friend requires a kidney transplant. I've heard that we are all equipped with two kidneys and can live with just one. How do I find out if I can donate a kidney? What's involved in a kidney donation? Thanks!
