At what age do we becone "old" or does that depend on the society you live in?

HiLesbehonesthere,
I'm a much older guy than your young years but I was wondering what expectations you have for a FWB type relationship.
I can't really see how I could enter into a regular intimate relationship with someone without having some degree of attraction from the outset. If there is a level of attraction the bonding that happens because of the repeated sexual act is bound to lead to higher levels of emotion above just simple attraction and that is going to be a difficult tightrope to walk.
I don't think I could walk that tightrope. I can see how short pure lust and sex relationships could work, using each other to work out your sexual needs and desires and moving on but to go on for longer and form a workable relationship where one party doesn't feel emotionally attached is I think nigh on impossible.
What is your view?

I haven't got a clue here, dropped in to the dating scene after a 25 year relationship and I really haven't a notion how to start?
