Anybody born in West Hollywood and given the name of "Lance" will definitely be born that way.
Nurture not nature. Cultural influences make this “Lance” behave that way, not biological instincts. Even if his biological instincts were so inclined, this hypothetical Lance you mention still chooses to engage in that activity.
So whether ones engages in normal heterosexual or aberrant activity, it is still a choice of the individual involved.
