Ask Dr. K

I'm a type 2 diabetic and my partner has been complaining after oral sex that lately I taste nasty. I would very much like to know what could be causing this and how to correct it as oral sex has become such an important part of our sexual relationship. We've been together two years and this is the first he has complained, though I've heard the same complaint years ago. Could this be an STD, a yeast infection, UTI, or is this a diet and/or blood sugar issue?

I have been too embarrassed to ask my doctor why I taste bad sometimes even though it has caused me relationship problems too many times over the years. Thank you in advance for your help.

Ejaculate is composed of water, sperm, prostatic fluids, small amounts of hormones and sugars. These fluids -- like any body fluids -- can acquire subtle smells or tastes depending on diet and the function of key body organs like kidneys and the liver. Certainly, changes in blood sugar could effect the composition of ejaculate as well as infections in the urethra, prostate or urine. As you know yeast infections are more common in people with diabetes for reasons that are poorly understood.

It makes sense to get a check-up to rule out any infections or changes in blood sugar and consider any changes in your diet that may have occurred.

Ejaculate can change over time with changes in hydration status, frequency of orgasm and unknown factors as well. Little research is actually done on this issue.

To your health,
Dr. K
