That is a very valid point, I should have phrased it in a more generical / biological way from the start. My hope with the original formulation was that it'd be easy to understand and relate to, but I agree that I should have put in more time to find a better way of saying it. As for the argument itself, I believe that novelty seeking in general might be an unintended side effect of that urge to procreate. That would also explain why people use words like "love" for new technical gadgets and develop a highly emotional and irrational attachment to their newest toy. Plus, there is evidence that the raw attraction fades more quickly for couples that spend more time together, which would suggest that one aspect of sexual attraction is in fact exactly the novelty of the partner. And since genetic compatibility is difficult to determine in advance, there would be benefits to a systematic exploration strategy.
