I think this question is like asking if Jesus would have enjoyed sexual intimacy with His wife if He had gotten married.

ANRs were widely practised, and were in fact the norm in His day so I’m pretty sure He would have glorified His Father and selflessly served His wife with this beautiful intimacy, were marriage on His earthly agenda.

See Why I’m now 100% convinced that Proverbs 5:19 is about Adult Breastfeeding, Am I twisting Scripture to justify my kinky fetish? and A biblical defense of ANRs for evidence that Couples Nursing was taken for granted, popular among ancient Israelites, and not at all seen as taboo during biblical times.
