As far as relationships are concerned, it's healthy if that's the relationship's dynamic. If you are more a "submissive" type, and this works then go for it. If though you are usually more "dominant", this will definitely create some type of tension that will need to be addressed sooner or later. In my relationship with my wife, I let her do the talking. Phone number, address, mingling with other parents at kid parties...Really the only time in public would be at the drive-thru only for the sole reason that I'm usually the one driving. I will say that the only time I *wish* my wife was able to order for me is when I go to Jamba Juice. Probably one of the worst places to having a stutter/block. Specially if you order a "Strawberry Tsunami No Peaches Sub Mango No Strawberries, Sub Raspberries...No No Boost."
