He will start acting woried in bed
There are no signs. If you are bisexual, no one will know for certain unless you tell them.
'I'm bisexual'
Same way you can tell if a straight man likes a girl. Usually they would admit to it, it act like they have a crush on that person
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!
If you fall in love with and is sexually attracted to both genders you are bisexual.
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
You ask her.
As far as I could tell, there is no indication in any of the ten main novels about him being bisexual.
There is only one way to tell: you have ask her.
