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.

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.

My boyfriend doesn't "pre-cum." Could there be something wrong? Or is it common? All the other guys I have been with have not had this problem.

1) I have asked this question to many sites with no response, but came (sorry:) ) upon your site which seems to be willing to post just about any question and answer them too, so here goes:

Is there a laxative effect of ingested ejaculate, or is it ALL in my head (oh gosh, another one :) )? I have found that when I ingest my own ejaculate, almost invariably within a matter of a few minutes, I have loose bowels.

2) My boyfriend and I have been exploring oral sex for a couple months — but I've only just noticed that when I swallow I seem to experience a bout of diarrhea within a couple hours of doing so. Is it normal to have diarrhea from swallowing ejaculate?

Is it true if a guy holds his urine too long it can damage the prostate and make it harder if not impossible to have boners or be aroused?

I am living in a residence hall, and I never realized this until now, but my bowel movements are really smelly. It has gotten to a point where if I don't find a place to do it secretly, it becomes a great source of embarrassment. Could I be eating something that causes my bowel movements to be really smelly?

The few times I have tried anal sex, I get a horrible case of the farts afterwards lasting hours. I do not have the ability to hold it and it's very embarrassing. Is there anything I can do ahead of time or after to stop this?? Thanks

For years now I've been digesting my meals within an hour or less. I am able to see whole food in my bowel movements of meals that I have just eaten. Any idea as to what's wrong?
