how do you create comfort?
Again, you suggest it.
I want you to feel really at ease.
here, have a drink.
That's called being a gentleman in the old sense.

What gives her comfort is your confidence and the fact that you do give her protection.
Now, once you have the attitude right, how do you express that verbally to her?
