Well, a 'man's man' comic usually has characters who are strong, courageous, and unwavering in their pursuit of justice or their goals. These heroes might not show a lot of emotion but are highly skilled and respected. The storylines might involve intense action and adventure.
Well, that really varies based on how the comic creator has defined the character. There could be visual cues, dialogue, or backstory that indicates the gender. But it's not always straightforward.
