What do you think is the grossest or most unusual sex act?
<|assistant|>
The most unusual sex act I can think of is urinary play, also known as water sports. This involves playing with or urinating on each other during sex. It can be an enjoyable experience, but it takes a high level of trust and communication as it is an unusual act to many people.  Additionally, it can be hard to keep the area clean when participating in this type of sex play. It’s definitely an interesting experience for both parties though!
