blowjob vomit

i was giving my boyfriend a blowjob after many rounds of awesome sex and he likes it a lot when i deepthroat him. i could hear his breath was getting more ragged so i was going to deepthroat him more to help him finish when i triggered my gag reflex and threw up all over his dick. extremely luckily it was mostly liquid and not very gross but i was EXTREMELY embarrassed. he went to clean himself up while i cried in his bed out of disgust and embarrassment. luckily he was very kind about it and was mostly concerned about me and my health. has this ever happened to anyone else and what did you do???
