Sex in a hot tub or pool is commonly depicted on TV and in movies, but how many of us have actually given it a go?

A lot, according to the 2015 SKYN Condoms Millennial Sex Survey. Of more than 5,000 sexually active millennials, 74 percent have done it in a shower or tub, and 39 percent in a hot tub or pool.

Though it might seem exotic, there are some hygienic (and privacy) concerns about doing the deed in these wild and wet places, so let's dive into the do's and don'ts of hot tub and pool sex.

Safety & legality

This should be obvious, but I'm going to say it anyway: Anyone who can't swim should think twice about having sex in a pool. Pool sex is fun, drowning is not. Be smart and stay safe. Don't engage in pool sex if intoxicated, and be careful not to slip or fall in or around the pool.

Privacy and legality are two other major concerns for pool sex. Don't do it where people can see you because sex in public is illegal; sex in front of others without their consent is a misdemeanor.

Stick to private pools and hot tubs where you can get as steamy as you want without interruptions, or police intervention.
