@Midnight_Sloth indeed. There are of course cultural differences, but normally as long as it is family (parents/siblings) then there is nothing weird being naked around each others. Rather, people who actually try to sexualize it are the ones I find rather strange. How are you going to look for ticks in the summer, if you don't have someone helping? Rather, pretty much anything you can't do/see yourself, how would you do that without someone helping?
And even if you don't have family nearby, its not weird to see friends naked either (so you can ask them to help you instead). Though you are probably better off either enlisting ppl of same sex or being young, lest someone decides to sexualize it (though if only one is the latter, then ppl will probably do it anyway. because people seem extremely degenerated like that).
