The grosest thing I’ve done is probably that time I had sex with someone who forgot to take out her moon cup after having her period. The smell was “not great”.

However, since it was a suprise for both of us it did not have this awful anticipation of having to do something disgusting. We just found out after the fact.

Another good contender was having to clean the shower in the morning after a drunk guy shit in it when we took him home the night before because he was laying in the street and not able to go home by himself.

Also very smelly.

The guy actually left the house before we woke up, but without his shoes. He also tried to access through the garden, even though that was a garden without access to the road. I still have no idea how he managed to get out of there. He never came back for his shoes. I wonder why!
