I brush my teeth regularly but, I was running late and had no time before i left and i know i had bad breath...we kissed for about 10 seconds so its not like he stopped RIGHT away..should I say somthing to him about it??..I really like him and think we could have somthing but i dont know if that ruined it, I really worrrieeeeeeed.

Bad breath is cool but not cool. There was this girl with halitosis I wanted to sex but she had a bf.
=( Also there was this gf I had 1 time and broke up with her cause I kissed her after she ate a ham and cheese extra onion from subway. That's a bad memory! But you ok..trust me he would have stopped if it was that bad. But other than that he's a guy and prob don't care it seems it was your only time without brushing so it happens. You will be ok. He will kiss you again longer next time. =)
