I hate to be the one to tell you this, but the bimbo routine gets real old, real fast. Instead of being the one in total control, you'll find yourself trying to figure out what she's really thinking behind those glazed eyes of hers — or if she's actually thinking at all.

An intelligent woman will constantly surprise you and keep you on your toes. She won't let you get bored of her. Besides, it's nice to have something to talk about between all that chandelier-hanging sex.

While we're on the topic, a great girlfriend has to be sexually compatible with you. For instance, if you're into S&M and she's more the "fluffy lingerie" type, that's a problem. The two of you have to be on the same page — or, at least, she has to be willing to wear leather and use a whip from time to time.

Of course, this doesn't imply that she has to know all the right moves straight away; it simply means that you and she have an undeniable attraction toward each other, and are able to communicate your desires verbally (or with physical cues). It is important that you please each other in the bedroom, or on top of the dryer — whatever the case may be.
