Is it bad to chew sugar-free gum? I heard the chemicals in them are bad for you to ingest?

I was hoping to wear plugs. You know, the earrings...but do they hurt when you put them in?

What is wrong with my face? It permanently looks sunburnt across my nose, cheeks and on my chin. Sometimes it appears worse than others. It is hot to touch and often bleeds. Typical rosacea treatments do not improve the redness or pain. I'm overweight but otherwise healthy. Thanks!

I just was diagnosed with minor scoliosis. I am 38 years old (today!). I do yoga and while at a retreat, was told by the instructor that it looked like I had a little scoliosis on the right side. I crack my back, neck, and so on. I mainly do this on my right side (the side I have minor scoliosis). I feel very tight if I don't do it, and feel better afterwards, but I just know it's wrong. I don't know if my cracking my back is worse with this problem, or if I do it because of this problem. I have tried to stop, but even when I stop for a short period of time (month), my right shoulder "pops" (not snaps or cracks like when I do it intentionally while doing certain activities, like push ups or bench press (and it will happen over and over). This also occurs on my right hip when I do things, such as leg lifts. What do you think? Will this possibly go away if I stop or are they not related?

When both of you have braces, and you do happen to get stuck together, is there any way to unhook without help from anyone other than you and him?

The Internet has lots of false facts on it. I want to know if I should consider all the health/drug/sex/emotional stuff as fact in science/doctor advice, and what areas are not so qualified in knowing. The reason being is I want to be more informed, and I don't like to be mistaken in passing along knowledge that I don't know to be credible or not.

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.
