In the interest of you ever being able to [censored] this girl... for christ's sake, yes, buy her a damn gift. If you've been with her for 2 months, I don't think jewelry or lingerie are a good idea, unless she wouldnt think less of you for the lingerie... and the jewelry, except in certain situations, leads to them expecting that sort of thing.

Get her something that relates to something she likes. Its christmastime, she's been dropping hints forever, if she's normal. If she's not - and perhaps, worthwhile? - then you gotta think a little bit. But jewlery and lingerie, when they don't mean anything more than jewelry and lingerie - are a bit forward at this point, unless you plan to make this a completely material relationship.

Wow, I feel long winded.
