lactose intolerance odor large amount of mucus when lactose is consumed.

so ive been struggling with this for about 5 years now, and have no idea what caused it to happen. i am a very fit teenage male, running 20+ miles a week, also have been lifting for 2 years. i am lactose intolerant, but my effects from consuming dairy are much different than anyone else that i know. when i consume dairy i produce an odor from my anus. strong enough to be smelled from 20+ feet away. its a constant odor, it seems from self diagnosis that its mucus, very clear goopy slime that leaks from my anus. to get rid of the smell i need to dispose of the lactose in my system, meaning going poop. at times i feel like i need to poop and go, but only thing that comes out is a lot of this mucus. the odor is horrible, and ive struggled with it for like i said 5 years now. with no answers from doctors i really have no idea whats going on. am i the only person in the world with this? or is there some way i can cure it so i at least dont have an odor when i eat dairy... thank you for the help
