If he's the right man, he'll fall in love with you. If not, move on.
When a man is only attracted to other men and not women they are considered gay.
Gay men fall in love with other men. Liking anal sex with a man can be a sign of it but only you know that.
If by "men" you mean straight men then yes it is entirely possible for a staight man to love a gay man or even another straight man without being gay himself. This does not mean however that the straight man suddenly becomes a gay man and neither does it indicate that the man is bisexual. It simply means that he is attracted to a certain male but is still strictly attracted to girls.
Because he is a gay man
Depends on if you are attracted to the men doing this.
No, although a straight man can love a gay man as a best friend.
Gay men already are men. They do not pretend.
No. A gay man is someone who is sexually attracted to other men. A eunuch is a castrated man (who may be gay or straight).
Breasts don't make a woman. Some women are flat chested. The men who love them aren't gay. Also, if men had breasts, they would be men's breasts. So a man attracted to men's breasts would be gay.
For the exact same reason that straight men love women.
Yes, because I was that Gay man she fell in love with.
No. Gay men have just as much value in society as straight men. In some cases, more so, because some gay men adopt the children that straight men abandon.
