Then allow me to ask you the following. If sexual expression, as you phrase it, has a possibility of causing us to choose an eternity without God (and by extension, an eternity without the company of our loved ones) as it may cause us to put sex above God, or to put another person above God, is that still a form of love? You seem to think it doesn’t cause that, and at worst is spiritually neutral if not good.
However, if sex could potentially cause the loved one to choose an eternity in Hell over Heaven, would you still call it love? I don’t care if you accept the proposition. But hypothetically speaking, if sex with your loved one can result in their choosing Hell, does your choosing to go through with it still allow it to be called an expression of love?
