As disappointed as I am with biphobia that comes from gay people who ought to know exactly what being discriminated against for their orientation feels like I can sympathize with them in a lot of cases . A lot of gay people have had their hearts broken by bisexuals who were really just straight people using them as a guinea pig for their little experiment , or sleeping with them just so that they ' ll have a story to tell their future partners so that they seem adventurous or sexy in the case of straight women , usually . If that was a gay person ' s only exposure to somebody that claims to be bisexual , it ' s hard to imagine them not being a little prejudiced or at least wary of dating bisexuals in the future , even though obviously not all people who identify as bi are like that .
