the point of the question is not to explore whether you would "do" your self, but if you could get along with another person that has the same behavior and personality traits that you have.
like for an example, would a clone of yourself be too needy or clingy to the point where it would annoy you? are you to selfish to make sacrifices to fulfill your emotional needs?
also, if you can't get over the sixual orientation hang up then just substitute the clone concept with a doppleganger of the opposite six that is just like you in every way.
I haven't been able to answer this question my self yet, i can get pretty clingy and i was thinking today whethor or not if my same level of clinginess would drive me away.
