Take it another way: would you prevent your boys from having one more erotogenous zone to explore on their partner when they are adult just so that you could explore it everywhere now? Would you be so selfish to be able to experience it now but prevent your kids from ever experiencing it?
So, perhaps we should cover ears, necks, and lips too? Backs too, can't forget that. No sandals. Don't forget men, too: They really need to cover up more. Especially their nipples. Beaches are going to be a real bummer and more uncomfortable. Perhaps we should require loose swimwear and increase risk of drowning while we are at it.
Nudity isn't going to take away any of these zones. You children are going to experience things differently than you, and nudity isn't going to encourage or prevent it.
