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.

Dear Alice,

I am seeing a guy I love and we are both thinking of consummating our relationship soon. We are both adults and this will be the first time for both of us. This is great, but also a bit scary in terms of the necessary protection.

How can having multiple sex partners be a risk factor for cervical cancer? What is the difference between having sex with one man one thousand times and sex with one thousand men (not that I'm planning to!) one time?

1) I tried looking for an answer to my question in the archives, but didn't find one. What I want to know is if it is normal that my boyfriend's semen has clumps (I don't know how else to describe it) in it? The semen has never been clumpy before, but the last time I gave him a blowjob, the semen had a chunky consistency to it. Should I be worried that this may be an STD, or is this kind of thing related to other things, and if so, what are they? Thanks.

2) I just realized a few days ago that my sperm comes out in pieces. For example, they are as thick as small boiled rice pieces... is there a concern to worry?

About six months ago, I experienced pain when urinating after having intercourse. Typically, I have pain/burning the first time I urinate after sex, but then the pain tends to go away or diminish. I am a 38-year-old male. I have no pain otherwise.

I was hoping you could answer a question for me about birth control pills. There is a history of breast cancer in my family (my mother). Is it true that because of this, it is unsafe for me to use birth control pills? A few friends have recently had condoms break during sex, and I am looking for a type of "backup" contraception system.

I have been a Type II diabetic for several years. I am now told I am beginning to show kidney insufficiency — is there a diet, or can you tell me where to find diet information of foods that a diabetic can use that are lower in protein and/or a renal diet?

I relocated to a new area within the past six months. Since then, I have been experiencing congestion in the morning and pressure in my sinus area, such as stuffed nose and difficulty breathing, at night when I lay on my back and in the morning. Although I do not have a cold, I seem to always have a small amount of drainage on a daily basis. Within the past week, I am sneezing quite a bit in the mornings and at night, my eyes are so itchy I can't help but rub them to a nice shade of red. I have never had allergies before, just for your info. Thanks for any tips.

I have had Crohn's disease for 16 years and am in remission right now. Recently my boyfriend and I have been toying with the idea of anal sex, but I'm concerned about it given my health issues. I have a lot of thickening of the terminal ileum walls and worry that the "trauma" of anal sex could set off a flare up and be painful because of the narrowing. Any thoughts? I'm way too embarrassed to discuss this with my male doctor. Thanks!
