So...I was just skipping about the net this evening and came across something that was rather weird to me. Sexual orientation. I know what mine is and has not ever changed or wavered in the least.

However I have noticed some people tend to be one thing in one place and another in some other place. If you claim to be straight, then you can't also say you are bisexual. You are either one or the other, there is no switching.

Same if you are hetero, or even Homosexual.

so....why do people do this? Say they are straight and then flip and say they are bisexual? Just curious.
