@Mehhh,
In just about every human characteristic (including sexual orientation), the spread follows the Bell Curve (look it up if you don't know what it is).
What you experience
may simply be one of the orientations on the extreme edge.
Or, it may be the result of childhood trauma of some sort.
That is to say, it is up to you (and if you so choose, a counsellor/psychologist) to determine if it's good or bad for you.
Just a word of warning - be aware that such an orientation may lead to compatibility issues
