If you already know that Christians would say what you want is wrong, then you probably know that what you want is biblically wrong? Its not a matter of judging you, its simple Christian discernment of right from wrong.
Actually now I think about it, it's not technically wrong. Although it became wrong because of the fall, but I figure that it will be permissable again in the new earth when we have a perfect body.
But the problem is here is I would have to believe that, and that's not going to help me at all.
Funny how you mentioned that the Bible is the source for moral understanding. We learn our right and wrongs from those very words you say.
I can think of a lot of morals that God commanded that are totally outlandish, and wouldn't be able to equip his flock today to do the same thing. Considering the fact that most Christian's would have a hard time with condoning such outlandish stuff. Which would mean that if they have a conflict if interests with God's moral system (In the old days) This would actually prove that real morality is born in us, and doesn't come from a book.
