Advice urgently needed?

You could sit on the sink and wash your @sshole out or if it's a community restroom go into the stall take a wad of toilet paper dip in toilet clean water of course and make your own wipe. If neither of those are options see if another lady co-worker has any perfumed lotion you could take a squirt of it and lotion up your @ss crack to cover up the stank. Have fun!!
