You guys are focussing on the wrong thing I think.
What makes you having homosexual tendencies is not whether you're willing to expose yourself to members of the same sex. I mean, soldiers have been doing that for centuries.
What matters is whether you enjoy having sexual contact with members of the same sex. If you enjoy it even a little bit, then you have some homosexual tendencies. If you don't, then you don't. It's that simple.
