Fart fetish🌬

My boyfriend has a fart fetish and it really creeps me out. He keeps asking me to fart on his dick during sex/in his mouth during oral/on his hands during foreplay etc. I haven't done it yet but he keeps asking so I've just been making excuses like that I don't have any gas right now. Should I break up with him? We're both 17 and have been dating for two years. He just told me about his fart fetish 2 months ago.
