It was routine and we the audience, could take from it that the fact both sexes were in decon together without incident implies that the future has gotten past a lot of sexual hang-ups and imbalances that still exist in the real world today.
Yes, I'm sure that's exactly why they put those scenes in, for us to come to that conclusion about the future.
I feel like that point would have been better made if:
1. the crew had been purely naked (of course, with the appropriate camera tricks for real-world actors)
2. the actors were filmed in non-suggestive ways
3. the introduction to the decon chamber, as LC pointed out, had not been about flirting in Broken Bow.
The first point would mean that, yes, there would be no hang-ups about nudity from the crew itself -- no shaming, no sex negativity, just a default form of body acceptance. It also would have helped, and I say this honestly, if less than physically perfect cast like Dr. Phlox were shown in there, too (and that's also something about Trek in general -- when was the last time we saw a more common frame on a woman in the franchise? Almost every woman on the show -- main, guest, or even background -- are all svelte. The same definitely can't be said about the men.) The second is very much about the producers' intentions with having the chamber in the first place -- if the direction is non sexual, then there's nothing intimate to suggest. The third, though, set the tone for the chamber for the rest of the series, and is the very reason why this thread was made. All because of that introductory scene, which was carried over by future writers and the viewers themselves.
But yeah, if the intentions of the producers for the decon chamber to show that humanity had risen above the point of naked shame and titilation, then the production would have been handled differently from the start.
