To be sure, being aroused by the male body is also normal. Not that everyone is or should be aroused by the same things.
You bring up an interesting point: What about disgust? It's normal in America (in the sense that it seems pretty pervasive) to be disgusted by nude bodies that we don't find at all sexually attractive.
I am hard pressed to answer that question.
I'm not attracted to men, but I'm equally disgusted seeing an essentially or actually undressed obese man or woman. On the other hand, a nude (or nearly so) and fit person of either sex doesn't disgust me at all. I'm not attracted to hot men, but seeing them naked doesn't "gross me out." I am attracted to women, but an out of shape naked woman is, to me, disgusting, and the fact that she's a woman has no ameliorative effect whatsoever. Fit folks -- ideally good looking, but that's not a requirement as goes merely seeing someone naked -- of either sex are easier on the eye than are out of shape women.
I found that out about myself when, in our early 30s, my wife and I visited a US nude resort. We'd planned to spend the weekend; we left the next morning after less than 24 hours there. We/I never again visited a nude resort in the US. (Others later -- why is it that nobody tells you what you need to know until after you go -- told us that US nude resorts/events just aren't places where hot people,
i.e., not more than ~5-10 lbs overweight or underweight, go.)
FWIW, at nude resorts, men unaccompanied-by-a-women just aren't welcome. I think that's part and parcel with what I mentioned earlier about the influence men have had on social mores. I think that sort of silly.
For instance, when you and your lady are chilling on the beach and some ripped dude walks by, yes, she's going to check him out. Then she's going to look at you and, well, you're every bit as ripped, so what's she going to do? Chase after that dude whom she doesn't know or think "I've already got that and it's going well, so I'm gonna leave well enough alone."
I can't speak for all women, but for the ones in my life, it's the latter. That said, I wouldn't suggest going to nudity-allowed places/events unless/until one's relationship is very stable and secure. Folks with inferiority, socialization and/or self-control issues probably also shouldn't go.
But how much of that is also due to the fact that all of us keep our bodies covered? And is it a strength to be disgusted by the naked body of someone you have no sexual desire for? Most of us would feel at least a little bit of revulsion to see one of our parents or grandparents nude. Is this a good thing? Do people in societies where nudity is common feel the same disgust when seeing a nude grandparent? Would an average Saudi Arabian person feel disgust when seeing their grandmother at the pool in a modest (by American standards) one piece swimming suit?
Red:
In general, I don't think so. In purely selfish sense, sure, I guess one could call it a strength...E.g., that disgust is what gave me the sense to never return to US nudist resorts, so, sure, it's an element of strength in that it kept me from wasting my time and money doing so. I don't think that's what you have in mind, but it's about all that I see as a strength to the noted form of revulsion.
Blue:
No. It's one's parents/grandparents and one's utter indifference about their bodies isn't a matter of whether one sees them nude or not; it's about their being one's parents/grandparents. What they wear or don't hasn't a thing to do with it...at least AFAIC.
As for how folks who daily existence occurs predominantly in the nude and what/how they think about it, I can't say. I'd posit that they think of it much as I've just above stated I do, but insofar as their culture and mine are as different as night and day, I truly have no idea if that's the case.
Pink:
Again, I have no idea, and I'm fairly confident that's going to remain a mystery to me. LOL That's just not a topic that's even come close to coming up with any Saudi or other Muslim whom I know. Neither is it one I'll bring up.
Indeed, aside from belly dancers, I don't think I've ever seen a Muslim woman not fully dressed...Actually, thinking back to a trip I took to Bodrum, the Muslim women on the beach wore outfits that one might roughly describe as pajamas. Was there a Muslim woman there wearing a bikini or one-piece? I don't know, but I didn't meet her and she was no one known to the wife, GF or children of my friends.
