I was studying in Texas,the US.When I tried to tell our professor that "here I am," I said "I'm coming." The professor can't be more embarrassed.

在美国德州读书。当时想向教授表达"我来了"，然后我来了句"I'm coming"。教授整个人都不好了。

"I'm coming" is often said bypeople when they are about to have an orgasm. It's a phrase heard on American tv shows and movies and it's used in off-color jokes. Instead,"Here!" or "I'm not here but on the way" is what the professor thought he or she was going to hear.

"I'm coming"是人在性高潮临近时说的话，经常在美剧、电影和有色笑话里听到。怎么表达才让教授听懂呢?可以说"Here!"(我已经到了)或者"I'm not here but on the way"(我在路上了).
