Sex in water, is it dangerous?

There are a few things to bare in mind : 

#1 Condoms + Water do not mix well, with all that water washing about the likelihood of it slipping off is highly expected.

#2 if your gonna have sex in water, it removes the natural lubricant so i recommend using some form of water resistant lubricant or  it could get very dry down there and even painful

#3 having chlorine washed in and out of the female dramatically increases their chance of infection, the vagina isnt designed to have chemicals like that inside it

Your safest bet is either using the bath, but this can be a little awkward if its quite small , when trying to perform possitions like missionary. i would recommend the shower if you want to get wet and steamy, but invest in some slip proof mats, the last thing you want is to be slipping over :) Hope this helped
