The Third Precept says we should avoid sexual misconduct. What is Sexul misconduct?
 
If we use trickery, emotioal blackmail or force to compel someone to have sex with us, then this is sexual misconduct. Adultery is also a form of sexual misconduct because when we marry we promise our spouse that we will be loyal to them. When we commit adultery we break that promise and betray that trust. Sex should be an expression of love and intimicy between two people and when it is it contributes to our mental and emotional well-being.
