I don't seem to believe you aren't into sex right now. I mean, you're location is alluding to going on a date. That date was extremely sexual, and you are very fascinated with it. Meanwhile, the love between Tifa and Cloud, which is beautifully developed in the lifestream, is extremely spiritual. It's not like Cloud's sacred locked up memory was, "Hey Cloud. My friends are gone. Would you like to touch THEM?" I bet that would be your sacred memory.
EDIT: two people lashing back and forth you say? I think this is funny.
