I have a question for you about sex that may seem a little silly. I had a cold recently with a badly running nose. My boyfriend and I started having sex. While we were having sex, my nose stopped running completely. After we were done, my nose started running again. Do you know the reason for this?

Wondering if there are any negative effects to masturbation while being sick. I hear it could be a cause of lower immunity levels, is that true?

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!

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.

I went crazy and started masturbating more than usual in the shower and then when I got out my foreskin was swelled up. Should I see a doctor?
