A lot of people think that I am bi, but not really. Sure I think of women as being beautiful creatures, but then I think of the plumbing, and then I think "...Nah, I'm not enthused over that." You can find people to be attractive without it being a sexual thing too. ^_^
Also so far I agree with everyone else. It's always better to be honest about who you are than to hide it. If that means you have to date someone of the same sex to find out, then so be it. ^^ And also I agree with the fact that you shouldn't care what others think. If they love you, they love you for who you are, not what you look like, or are into. ^__^ So just be happy and not too hard on youself, ok?
