try a three way honest chat. talk to your brother, ask why he has such an issue with this. also talk to his friend and see if your brother has given him a reason to stay away, or a reason your brother is so protective.
I've had a friend date someone double her age, the way i figure it is each to his/her own. as long as the Guy is respectful of your wishes age should matter to much. (although i think double your age is a little gross personally. like dating your own father *shudders*).
It'll all work out right in the end. sometime you just have to sit back and see where the path of life leads.
