Yes I lurrrve curly hair on guys and always have, even when I wore mine straight.

It depends on how curly your hair is, but you could probably get a relaxer ().

If you have a loose texture maybe you could wrap it to make it look straighter.

I've also seen curly men use a ton of gel to slick it back so it looks looser/straight, but of course that'll be out of your face and not like the pictures.

I personally don't like to see obviously straightened or relaxed hair on men. And in the summer it'll probably end up having that obvious relaxed wavy look when you sweat. Curls look so much better than that IMO.
