Just by looking at her you can tell she'd be boring in the bedroom. She's classy, conservative, ladylike and a starfish in bed, only participarting in vanilla sex. She'd be horrified at the thought of giving a blow job. Asking her to partake in some anal action would have her shrieking "You Wanna Put What Where?".
Guy: "Look at that chick, shes fuckin hot!"
Other Guy: "Yeah but she'd be one of those You Wanna Put What Where Girls"
