Embarrassing!!

So, lately my husband and I have been busy and tired so we haven't been very intimate lately. We finally had time to spend with each other. he was kissing me all over and started going down on me. Right before I was about to orgasm, I farted. It was loud and I was mortified! He was very supportive and kept going but after that I couldn't reach an orgasm. I just got a shower and then went to bed. Has this happened to anyone before?
