John987 Frankly, this sounds more imagined than real. But, some breath odors come from the lungs due to inhaling odors. Take several deep breaths and exhale completely in the morning in addition to the mouth hygiene Annie suggests.

Kurt_Stein I heard that the guy who played Screech on Saved By the Bell had a similar problem. Back in the late-90s, he was apparently dating his co-star, who played Mr. Belding, and would suck him off during lunch breaks. When he returned the the set for the afternoon, he had a bad case of "**** breath." I heard that his remedy was to use lots of mouthwash and chew gum. I hope this helps!

Vicarinatutu Maybe one of your partners had chlamydia or ghonorrhea and it is now in the back of your throat. Just saying that it COULD happen. Maybe trichomonosis can live back there too? Just a guess. A PCP may have a swab for a throat sample to send away for a C&S and also you can give an STI to someone orally. Using condoms 100% of the time can help prevent transmission of STDs and also penis breath . But then you would have condom breath
