I think your manners are charming toxic they cost nothing and everyone can own them, they are universal and certainly makes a girl feel very special. I mean look at this:
The girl gets all dressed up for a wonderful date you know nails, hair, new underwear (just in case haha) gorgeous new dress, that mind you she has probably paid a fortune for and dieted for weeks to fit into. Perfect make up looks a million dollars only to have the guy across from her carry on like he is on a camping trip with his mates. It really has happened to me and I felt soooo embarrassed. I myself pride myself on knowing what cultery to use, what glass to drink out of and knowing not to pick up the bill when it comes. I also know that when the bill does come it is polite to excuse yourself to powder your nose. Or if you both need to leave then to stand behind the man while he does the financial paperwork. I feel really embarrassed for the guy when the girl is breathing down his neck while he is paying. For one it is rude to stare into someones wallet and two if he hasnt got enough money or for some reason his credit is not good, without an audience it gives him privacy to work something out with the matrade. Just IMO
Now for the wine thing I think it was just assumed that the man would order and taste, these days I think it is ok for you to ask your lady. I personally feel quite special when I am looked after and dont really have to think about the wine list.
Hope this helps xo
