Duh. Men are revolted by other men who dress, speak, or act in a feminine manner.
Actually to a real man, that wouldn't matter. A real man would be comfortable with his own sexuality so that it wouldn't bother him. An insecure boy would have issues with it. Also, being a real man has everything to do with how you carry yourself, treat others and your actions.
A real man stands up for what they know is right, even if it means standing alone.
A real man is quick to help and protect those who needed it
A real man only judges someone by their actions and how they treat people
A real man strives to be a good role model for those around them
A real man is dependable and their word is their bond
A real man does whats necessary and if it means making the hardest decision possible or a unpopular one
A real man respects women, period
A real man is mature and respectable
I could sit here for the next hour and continue to type out what makes a real man, a man. But I simply do not have the time. So I'll close with this, Just because you are male and 18 or older does not mean you are a man. It is also 100% possible for a woman or gay man to be more of a man all of the males around them. Because being a real man has little to nothing to do with being able to grow a beard or having something dangling between your legs.
