The cute vs sexy thread reminded me of this.
I had an argument with a co worker years ago. He argued that a woman (we are strait men) can be sexy even if she isn't pretty. I disagreed, I said sexy means sexually appealing and to be sexually appealing you need to find the woman pretty in the first place. He never explained himself well... just to him pretty and sexy can exist separately, I think sexy REQUIRES pretty to exist.
What do you think? It doesn't make sense to me that you (we are talking you here) can be like "she isn't pretty... but yeah she is sexy"
