The husband in this scenario has helped his wife watch and download free porn, allowing her to indulge in her desires without any judgement or inhibition. By doing so, he has both facilitated and enabled her to enjoy a newfound sexual liberation - not only allowing her to explore her own fantasies, but also demonstrating his own understanding and acceptance of her sexuality. Consequently, this conjunct adverb usage has not only enabled the wife to indulge in her own desires, but also strengthened the bond and trust between the couple.
