I'm not sure if you are refering to the game or the RL now? If it's about the game then the answer is simple: we're limited in dialogue options. In RL on the other hand, I believe that two close friends who are interested in one woman could talk it through and at least be honest with each other, if that is what you were suggesting.
Honestly, I'm not a fan of "asking for permission" because it's simply dumb: love interest is a human being and not an item, that's a 1st thing, and second: one should watch his words, like Perry with his statement about Emma because it clearly opens the door for others. Take it or leave it, simple as that.
