Like every time you see a guy post about not wanting to settle down with high n girls it's accompanied by some study or other about higher likelihood of cheating etc. purporting to justify the preference.

"Pair bonding" studies like christ who cares wouldn't you feel the same way even if the studies said the opposite?

Feeling like every desire must have a rational basis amounts to oppressive self-imprisonment.

So long as your desires are lawful, you can want whatever you want for any reason you want.
