Does swallowing semen cause bad smell for breath?
Patient: Can swallowing semen on a regular basis cause bad breath? I'm in my early 40's, eat a well balanced diet, follow a good dental regimine (floss daily and get teeth professionally cleaned every 4 months).  At times my breath smells like spoiled meat / eggs.  It's really embarassing.  I enjoy oral sex and swallow semen at least three times a week. Doctor: Bad breath occurs due to reasons apart from poor oral hygiene. Gastric problems, sinusitis, respiratory problems, liver disorders, consumption of onions, garlic can result in bad breath. Identify if you suffer from any of these problems and consult the specialist.
