Last night, while my husband was about to insert his dick

Last night, while my husband was about to insert his dick into my ass, I farted! I was really embarrassed, because the sound of my fart was too hight, i think even the people who live next door heared it, not only that, but the smell was awfull too. i quickly left the bedroom with embarrassment , my husband came after me and told me it was ok, but i felt ashamed and i started crying this was the first time he wanted to try anal sex with me, and i let him down he comforted me, hugged me and kissed me, but i could not resume back out lovemaking anymore the more i think about it, the more i get upset and embaressed what should i do?
