Genetics or environment?

If there were any reason for me to swing both ways, this could be one…..

I adore my parents.

Damn….so much confusion! Hahahaha. Okay the pictures above are of my parents. Dad’s in slutty make-up and Mom’s in hamsap pontianak do. So my point was, if I were to become bisexual, the reason could be this. Just that I’m not too sure whether it’d be genetics or environment. Oh well, never mind. *Yawns*
