After having anal sex with my partner, I noticed blood on him, although there was no sign of external damage. The next day I am feeling pain internally, but I can't pinpoint its location. What are the possible dangers and should I see a doctor?

I've been a good kid working out and being healthy, but the gym I go to has uniforms and I always wear a black t-shirt. That's great, until I sweat and it leaves salt rings where the sweat reached out to. Ewwww. This is embarrassing, and I have to wash the shirt before I can wear it again, which is annoying since I go almost every day and need to re-wear shirts once or twice. ANYWAYS, how can I reduce the amount of salt in my sweat, and prevent these embarrassing white rings from forming on my clothes? Eating differently, drinking more water, help!

I get cold sores around my mouth and nose all the time; I have since I can remember. I know that they can be caused by both physical illness and mental stress. Is there any way to reduce the frequency with which I get them, i.e., diet? Please help me, I feel like a leper.

I have had terrible stomach problems for a few years now. My doctor says it's due to my love of greasy and oily foods, and that I should concentrate on eating healthier, broiled foods. Do you think if I continue on this unhealthy eating cycle, that I could develop gallbladder problems? Also, do you think my diet contributes to my acne-prone skin? Thanks for your help.

I work ten-hour days, four-days-a-week, standing in one spot. The bottom of my feet feel like a lot of needles are pricking my soles. Could you please tell me what could be causing this? Just started about one month ago.

1) For like several years I have been afflicted with a really smelly crotch. It's like I sweat a lot down there and it just has a really sweaty vaginal odor. I bathe regularly but nothing really helps; by the end of the day I always smell funky. This wouldn't gross me out if it was just an occasional problem, but it happens every day. What can I do?

2) I have an embarrassing odor problem in the crotch area due to sweating. The odor is the same as underarm body odor. FDS didn't seem to help any. Cornstarch and powders work for about an hour. I wear only cotton panties. It seems that gel deodorants (Mitchum/Soft & Dri) are the only products that will control the odor for more than one hour (not long enough). Is using antiperspirants/deodorants harmful to my body (I do not use it in the clitoral/vaginal region, only on the "mound" of hair)? Also, how can I eliminate this sweating? My friends don't seem to have this problem. I am 32 and the problem seems to worsen each year.

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!

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!
