If you're doing your work and something NSFW pops on your screen I doubt your boss will give a fuck.

If you're spending your time watching NSFW stuff in your work time he'll probably be mad, not because of the NSFW stuff but because you're not doing your work.

We don't have issues with nudity on prime time, although explicit stuff tends to be shown after 11pm.

In some countries sex shop contents are visible from the street, and you can buy some kinds of toys on the local supermarket.

And to be honest there is hardly anything left to hide when being at the beach or some parks.
