I'm being teased a lot by this girl about this and its bringing up some interesting questions.

I have no idea where the line is drawn between I'm being a gentleman and I'm being a sap. This is dealing with WOMEN, not exactly just a date. Female friends too.

Opening doors
buying flowers
paying for food
letting them sit in the front of the car

Those are some things I've been teased about and that I dont do them and am poor mannered not a gentleman etc. Im not sure how to take this. On one hand as I said i dont want to be weird and wimpy, but i definitely do have trouble knowing how to treat a girl even if shes just a friend like a female.
