I'm straight,
I'm a guy and while I can think of either sexes as attractive being gay is just wrong. If we were supposed to be Bi then we should all be able to reproduce asexually, since reproduction is the reason for sex.
Then why are so many animals in the world gay or bisexual? Obviously it must be natural then.
Reproduction is not the only reason for sex. Look at the binobos (apes related to chimps). Withing their society, they use sex for many reasons, including calming down aggitated binobos, bonding, and to ease boredom. AND... they are bisexual as well. They'll even have group sex, verging on orgies.
Hmm... sounds like we're not that far off.
