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.

I have purchased a set of stoneware dishes for a friend for Christmas, but my family has told me that stoneware (even when microwave and dishwasher safe) can be harmful due to a high lead content. Is this true of all stoneware dinnerware? I would appreciate any information on the subject. Thanks!

I'm HIV positive, very low viral load & great t-cell count (not on meds). I've been reading recently that flu shots aren't all they're cracked up to be. What are the dangers of a flu shot, and if my immune system is already doing well, should I still get a flu shot?

How and what does the human body do with the petroleum based skin products we apply to our bodies on a daily basis? I'm sure a lot of these products are absorbed through the skin. What does the human body do with them? Can it break them down? Do they just flush through our systems? What happens after they are absorbed? What are the long-term effects of using these products? What are the health risks?

What causes constant fatigue? I read that iron-deficiency could cause it. With all these new diet fads and push for dietary supplements, is there anything that helps or hurts energy levels (ex. eating or not eating carbs, taking or not taking certain supplements, etc.)

Thanks!

After many years of confusion, I have been diagnosed with trimethylaminuria. It is an awful disease that has caused much emotional pain in my life. I was hoping that if the disease was discussed on your site that people's awareness may increase and perhaps people would not be quite so quick to judge others. I would appreciate it if you could post my message for this reason. Also, if the disease is caused by the lack of a certain hormone in my body, then would an injection of this hormone be a possible solution? In all of my research, I have not seen this discussed.
