Any hair long and straight enough to run my fingers through. It's so relaxing to just be able to cuddle up with someone and be able to comb your fingers through her hair. I like being on both sides of that actually, it leaves my scalp all tingly lol.

As for color, I've always liked the lighter ones in general.

Longer, brunette hair with bangs definitely seems to be my favorite. I'm not too picky, however; I like whichever haircut suits the girl, which is usually the one they feel comfortable with.

I gotta admit that I'm not a fan of pigtails, though, like, at all. Luckily these are not a permanent hairstyle. Oh, and I'm not wild about gaudily colored hair, f.ex. pink, green or something like that... but, of course, if the girl's hot, I probably won't care.
