Someone that's very promiscuous usually doesn't care who they get sex from but there is no sure sign because all humans act differently so you can't generalize on something like sexuality
None. There are no signs. Also, consider these points:There is no such thing as "bisexual tendencies." A person is either bisexual or they are not bisexual.A heterosexual man cannot be bisexual (by definition of "heterosexual").The ACLU doesn't care about a person's sexual orientation.
There aren't any signs other than direct observation of same-sex behavior. You have to ask the man.
There are no signs. If you are bisexual, no one will know for certain unless you tell them.
he checks out other guys, flirts with them.
Whether or not the man is bisexual is not really an issue. A bisexual man can be just as monogamous and faithful as any other type of man.
Well, think about it. Man- Bisexual, so can have either man or woman. Woman-Bisexual, so can have either man or woman. The man can have a woman. The woman can have a man. Therefore, they can have a "straight" relationship.
This man speaks for himself!
First of all, sexual orientation is unchangeable. If a man is bisexual, then he will always be bisexual. Secondly, a bisexual man is by definition fully capable of loving his wife and being attracted to her. But if the man is actually gay, then that is a different matter altogether.
Obviously
There aren't really any signs. You just have to ask your friend.
If a man is gay then he's not bisexual, then he's gay. Right?
If he likes men, he is homosexual. If he likes woman, he is heterosexual, if he likes both, he is bisexual.
