Let us just think about whether you have ever been attracted to a member of your own sex. Be brave nobody has to know about the details, the only thing been asked is for you to be honest with yourself. Have you fantasised about having a sexual adventure with someone of your own sex. It would not be as if you are the first person to do so, in fact some may argue it is health to do so. Personally, I agree, however do not get hooked up on guilt or fear that it is somehow abnormal to have these feelings and in some cases act on them. It would be unhealthy not to, if you act to repress these feelings it can lead to disaster. Alternately sometimes, we do have to play it safe in real life, but that does not mean you need to deny your personal fantasises.
