My brother has a girlfriend that I'd like to date - is it possible or ethical for two brothers to date the same girl?

The ethics of this situation depend greatly on the nature of your relationship with your brother and his girlfriend. Are you close friends, or do you have a closer relationship with your brother? Do you have an agreement with your brother not to date his significant others? Do either of you feel uncomfortable with the idea? Considering the complex nature of familial and romantic relationships, it is best to speak with both your brother and his girlfriend to work through your ethical concerns together.
