And I Am A Guy..
I don't straighten my hair everyday. I used to do it everyday, but that just took too much time and ended up ruining my hair. My hair is naturally wavy and now I just blowdry it. On the weekends, I usually straighten my hair one or two days if i'm going out with friends and it looks amazing. I don't think there is anything wrong with a guy straightening his hair. It's nice to be able to have that option and I think it makes me look more attractive.
