As long as it's legal, live and let live, imo. Life is too short.

Though I also encourage people to not rely on it as their only outlet for being horny. It creates unrealistic expectations around nudity and sex, which is irritating in certain scenarios.

It's extremely apparent when someone thinks nude beaches are for sex because they've watched a shitload of porn and start acting out. Everyone else is talking with friends, reading books, or getting some sun.

If you want to do voyeurism, go to your local kink events, there's plenty of them through FetLife.
