I am a graduate student and have been using Health Services for a number of years. On recent visits, I couldn't help but notice a certain nurse practitioner on whom I now have a big crush (pardon the school-kid terminology). On my last visit through walk-in, luck would have it that I got this person to treat me (a random happening--I didn't choose it in any way). I felt somewhat awkward during the visit, yet happy to see this person. Nonetheless, I realize that this is not an ideal state of affairs, but I don't know how to handle it. I am due to return to this same N.P. for follow-up.

Should I tell this person that I feel awkward receiving medical treatment from someone I would rather be dating, or should I just make an appointment with another person? Would it be possible to seek medical attention from this person after letting them know how I feel? If I do end my medical relationship with this person, how would I begin a different one? There don't seem to be many occasions when students and the Health Service staff interact outside a medical setting. I would hate to pass up the possibility of meeting that someone special due to professional constraints that would not hold had we met under different circumstances.

Is it safe to have oral sex when either partner has a canker sore — not a cold sore, but a canker sore? Does the same virus cause both and can you cause genital herpes with a canker sore?

I've been with same pain specialist for 10 years. He wrote me a letter and dumped me as a patient. Why did this happen? What can I do?

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.

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.
