AITA for lying to my boyfriend about getting pink eye?

I (F28) have been dating my boyfriend (M29) for four years, and this guy farts a LOT. He could power a hot air balloon with his farts, he’s just a gassy man.

Last week we were 69ing, and he thought it would be funny to fart in my face one inch away from my eyeballs not once, not twice, but thrice. I’m an easygoing person, so I wasn’t horrified, but still, what the fuck??

Three days after the incident, I told him I had to go to urgent care for pink eye from him farting in my eye, and I kept the schtick going for roughly five days until I fessed up last night (we don’t see each other very often due to our work schedules, so he never saw my “pink eye”), and now I feel bad for lying to him for so long.

AITA?
