I actually did have all the symptoms you mentioned. I always did think I smelled worse after a bowel movement and I still try to only poop before a shower. I dont put hibiclens up my anus so I cant comment on that. Yea the smell will come back if you stop using it. As a matter of fact after a few hours (like 5-10 hours depends) the hibiclens starts to wear off.
I had the same problems as you my infection would always come back even when I used anti fungal wash, it wouldnt go away. Hibiclens has been effective in keeping it away.
