Why are men afraid to be gay?

Instead of embracing it, they hide it and lead a false life. This is not good for everyone especially you. We meet them, we fall in love and maybe we will never find out, or maybe we will. In many society, it is not right for the man to be gay and have relationships. This is why so many of them hide it, it is disgusting and not natural. How is this supposed to be? BE yourself and love who you are and not hurt the people that are in it.
