your age is relevant if you intend to use the words 'do you want to go out with me'.
its juvenile and saying it to a woman is ridiculous. when you ask a woman to go out with you, you are saying it to literally ask to go out, once. you dont ask a woman to go steady either, this is all teenage bullshit.
if you want a woman to be your exclusive romantic company, you sit down with her and say so without using the phrasing of a high school child.
