I have a cousin and he's gay. I have been watching him for a long time and it seems to me that he is a very unhappy person. He is always lonely and can't find a partner at all. Why are gays so lonely?
Not everyone can easily get acquainted in everyday life. Perhaps someone lacks sociability or he is shy to start a conversation. I will give you a good advice so that your brother tries to use the dating site adam4adam adam4adam, which is designed exclusively for gays. This is a really great place to find partners and they pay a lot of attention to user safety, so let them try and join for free.
Not only gays are lonely. Loneliness is a real problem for many people. But fortunately, the online dating industry is developing.
