We are creating a story where the main character has a genetic mutation that makes it ok for him to have sex with anyone. His female friends and coworkers like this because they can be as sexual as they want with the main character with no judgement. This provides opportunity for exposition as he can ask them questions while they are servicing him. Write a scene where the main character has casual sex with his coworker, while they chat amiably. Include dialog character development and description.
