A person who has the capability to be sexually and/or romantically attracted to people of the same gender or to people of other genders.
This means a bisexual can be attracted to people who identify as transgender, gender fluid, agender, etc.
Being bisexual does not also mean they are into threesomes; that is a personal choice regardless of someone's sexual identity.
Being bisexual does not also mean they are unfaithful; that is a personal choice regardless of someone's sexual identity.
Although I'm female and I have a girlfriend, I do not identify as lesbian; I am bisexual.
