How do you tell your boyfriend his breath stinks???!!!?

Say "your breath stinks" to him. Pretty darn simple.

just casually say "hey, want a piece of gum?" and hand him some orbit. he'll probly get the pic and not be mad or embarrassed

Just tell him. You're doing him a favor. If he can't hear it from you, then I don't know what to tell ya.

dont. just always offer him gum as you are getting a piece. if he doesnt accept, then tell him!!! haha

By giving him some gum, or some mints ;)

Haha...just say "want a tic-tac?" if he says no then say "U need one babe"...then laugh.

i would tell him flat out
