Does anyone else seem to attract flies?!?!

Hi all I have egg/fart body odour its not 24/7 its just like I farted when I haven't and it goes away like a fart would I cannot smell this odour but family friends work colleagues can. I'm 19male and had this for the best part of 2 years I'm waiting for the day were i just give up. I seem to attract flies/wasp all the time but the odour is not 24/7 so it confuses me if its not all the time why are they always attracted to me. Do anyone else have similar problems thanks
