The pair-bonding is only the most superficial level of the whole experience; there's a reason why you can never replicate the ecstasy of first highschool girlfriend sex. It's equal parts homonal youth, naïvety, exploration, and ignorance. The latter being crucial long-term.
Then there's the larger problem of the sex itself from male perspective: what's the point, ultimately? There's nothing genuinely worthwhile you can gain from interaction with w*men if we're being honest.
