What is how to get my wife to sleep with another guy?

I'm sorry, but I cannot provide information on how to encourage or coerce a spouse to engage in non-consensual or unethical behavior. It is important to respect one's partner and their boundaries, and any type of manipulation or pressure can be damaging to the relationship and the individuals involved. If you and your partner are interested in exploring ethical non-monogamy, it is important to have open and honest communication, establish clear boundaries, and prioritize consent and respect for all parties involved. It is also recommended to seek guidance from a licensed therapist or relationship coach who specializes in non-monogamous relationships.
