First, I want to share interesting fact, some of the science studies said that everyone, any of the living objects, are bisexuals in the nature.
And yes the bisexuals like both men and women, also bisexual can be the guys or gals. Some of homosexuals and heterosexuals dislike the bisexuals because of the suspected of cheating, because there are some people that marry with opposite sex and have family, then also have another same sex partner just for sex.
However, that give the bisexuals the bad names because those actually have nothing to do with the status of bisexual, but has something to do with their relationship strength.
Also there are some of people became bisexual at young age, trying to curious if they like it or not. Some people went back on straight or homosexuals, or just staying as bisexual.
That's all I can say about the bisexuals
