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

It would be ethical for two brothers to date the same girl as long as both of them are informed about the arrangement and all parties involved consent to it. As long as they are transparent and open with each other, it should be acceptable. Just make sure to respect the boundaries and avoid any potential drama or confusion.
