I&#x27;m wondering about that, too... but I&#x27;m beginning to suspect that this is the wrong question to ask. It sounds a little too much like sexual objectification, and a little too much like eugenics; it&#x27;s probably the wrong way to go about dating and marriage...<p>Not that this is an endorsement of the &quot;transient, lawless, chaotic sexual desire will find a way&quot; ethos of rock-and-roll, of course.
