I liked trimmed by a large margin, I like the feel, it looks feminine and sexy.
Completely au natural is a bit much, and suggests a lack of effort.
Completely shaved or bald, no thank you. First of all, the hygiene argument is complete and utter bollocks. Secondly unless it's freshly done, stubble is unpleasant. Thirdly is just aesthetic, I prefer the post-pubescent look not the plucked chicken.
