Why does my anus has a bad smell even though i wash and wipe it every time i go to the bathroom i'm constipated and have ibs. what shall i do?

Prolapse?: Ibs can cause rectal prolapse, which can cause your symptoms. Be seen to be evaluated.

By covering your : Nose , you would smell less! (pun intended) . When you're constipated & when u eat more meat than fruits and veggies, you accumulate more waste products causing the foul smell . Here are my suggestions - drink lots of water mixed with prune juice, also take stool softeners and/ or laxatives to have daily bowel movements
