Yesterday I was rimming my girlfriend and she came so hard she farted in my mouth. 

I didn't really care but she freaked out. I mean I kinda involuntarily gagged because of the air but I wasn't bothered. Like I was eating her ass right after she did a 6 mile run, I don't care about too much. 

Now she ghosted me. She went home and will not answer my calls or texts. 

What should I do?
