>everything reeks of shit the moment my cheeks get close to parting
How do I fix this /fit/?
Is it my diet?
You should try taking a shower every now and then and Washing your ass.
Also you probably have a bunch of hair that acts as a satefy net for any turds falling in the toilet after which you smear it around with a piece of paper.
I.e. dont be a gross subhuman and exercise personal hygiene
Is there a proper way to wash your ass? I always adjust the shower head so that the water comes out in a narrow, high pressure stream, and then bend over, stretch my ass, and have the water blast my asshole. It cleans it up great, but can be painful.
Get some soap, lather up your hands, and reach around and wash your ass properly, getting thoroughly into the crevice.
Rinse well. Congratulations, you now wash your ass in the shower like hygienic adults do.
