shove a piece if gum or two into his mouth every so often lmao but yea idk how you can kiss something that smells like that you should probably advise him about it.

Ohhh been there! Just tell him that his breath isn't as fresh as it could be most of the time. Nobody likes having bad breath so he'll probably thank you later on.

20, in that case, wouldn't a doctor be better to see? I don't think a dentist is going to kill a disease you have... But OP, speak up. Let him know that his efforts to try and get you used to what the bathroom will smell like once he's finished with it is just disgusting you.

That stinks

Put listerine In you mouth and than spit it in his mouth.....it's like a orthodontic snowball....

True, it could be a much deeper issue... Definitely tell him, and then if flossing, brushing and mouthwash don't help a trip to the dentist and/or doctor is probably in order. But certainly get him to floss regularly - meat and other gross stuff can get stuck between teeth and literally rot, which does indeed smell like swerage.

It could be halitosis or rotting teeth. You should nicely suggest he see a doctor or dentist. you would be doing him a huge justice. Chances are, you are not the only person that notices this.

Remember that Spongebob episode when he thought he was ugly, but his breath just stinks?

Tell him if he's into kissing so much, he needs to go to your other lips. Odds are the smell down there is on par with his mouth.

Get that poor guy a dentist appointment.
