take her to a sex shop, she'll love it. Then go to maccas, get a happy meal, and share it with her, she'll love that too. Oh and take the toy.
Dinner and a movie is usually best bet *Shrugs* common interests would help
Or, do something, different? Do some dougheys in your car with her in it, go paintballing(was meant as a joke but hey, she might like it ), take her on a pub crawl, a pub with lingeret weitresses, strip club, brothel, pick her up in your car with your "bags packed", food and water and a tomahawk JUST in sight and grin like an idiot. Shall i keep going?
