I wasn't qualifying anything for you. Anybody is free to take this topic wherever they want.
And why would there be any age range under that scenario you posted above? Physical attractiveness would be the only thing that mattered. But yes, my posts is this thread are more focused on talking about dating as it relates to actually wanting to be around somebody and not knowing where it can lead. If that includes sexual motivation within those bounds, then that would be your own perogative, but if your ultimate intent is to just to use and bail on somebody, that's not dating to me. It would make you a selfish prick if the other person wasn't aware of what was going on. Or it would make you both stupid in my book if you both knew that was the ultimate outcome and wasted time doing anything other than getting jollies from each other.
