Is it legal to require fulfilling intimate need, wants, and desires in a work contract?

I have been hired as an employee at an adult entertainment company. (not the entertainer. im behind the scenes) In this contract that he has written requires me to fulfill his intimate needs, wants, and desires. He also requires for me to be affectionate to him at all times. Isnt this illegal? I haven't signed anything yet. I want to know if this is illegal first so that i can fight to get it off the contract
