Sounds just like my (otherwise wonderful) boyfriend who said I look 100% more attractive with my hair straightened and anyone who said otherwise was lying. Then he backtracked, and said he only "prefers" straight hair. So I replied that I "preferred" guys with a six-pack but what am I going to do because I'm with him. I haven't heard a peep since that, and he's even gone out to buy my curly hair products for me. Stand firm and if he makes it much of an issue, be prepared to defend yourself. It gets easier, I promise, once he puts things in perspective and realizes that its YOUR hair not his. Best of luck
