I personally prefer straight hair most of the time although soft waves can look really nice too. I have seen some women with really curly hair that looked quite attractive however. I think it really depends on her face and how the hair frames it.
Every guy likes something different, I go nuts for long straight hair, but I know people who do the same for short curly hair. The only thing that any one guy can say for certain is that it needs to be a hair cut that fits you.
You know what looks great to me... straight hair about up to the middle of your neck...don't get me wrong though- curly hair can look great on some girls but if I had to choose it would be straight.. Bangs are sexc on some girls too..
The opposite of what you have it usually. I have big curly hair but always straighten it so he prefers it natural. Also the one which the least maintenance so you don't throw a bitch fit when he touches it.
