Seriously man, just hit her the head with your club and drag her to your cave. Simple, good logical approach.
Although really, you sound like your pretty young, and this is something you should talk to her about in person if you can, if not phone will do - its better to get it out in the open rather than bottling it up. Endgame is, don't force her to do what she's not comfortable with, that turns you into a not very nice man at all, just be a gentleman.
