Skinny Dipping: From the Secret Naturist Handbook:
For the secret naturist, skinny dipping offers a way to make secret naturism acceptable in the eye of the general populace. Anyone witnessing a naked man, or woman for that matter, skinny dipping in a river, pond or the sea, will usually not take offence. People do not generally see any risk to themselves when someone is skinny dipping. This acceptability also means skinny dipping is a good way for beginners to get into secret naturism.
I must admit that I'm not really into skinny dipping in the true sense of the term and tend not to actually swim very much, mainly because the waters of Scotland are usually too cold for full immersion. The one exception I have found are smaller sized ponds which can often be quite warm during the summer, Generally though, I tend to enjoy simply wading about in streams and rivers, and the sea, rather than actually swimming. But each to their own.
There are many places where skinny dipping, in whatever fashion you prefer, is possible. The countryside is dotted with all manner of rivers, small streams, reservoirs, lakes and small ponds, and of course, there is always the sea. As a rule running water will be colder than still water and smaller bodies of water will have a greater heat gain during the warmer months than larger bodies of water. So, for comfortable skinny dipping, look for smaller ponds and streams.
There are a number of factors you need to consider from the secret naturist point of view when skinny dipping. The first is dealing with your removed clothing. Whatever the location, you will be separated from your clothing while in the water and you need to make sure you clothing is secure. As a rule I always hide my clothing when skinny dipping. Should someone stumble into the area, at least my clothing is hidden from view and I only need remain in the water to conceal my nudity.
Another point to consider when skinny dipping is that even the freshest cleanest looking water will leave a lingering smell on your body. For some this might not be a problem, but for those who keep their secret naturist activities a secret, this can be noticeable to others. The beds of rivers and the bottoms of ponds can also be quite muddy, not to mention smelly and you should be aware of this.
Safety is an important point when skinny dipping. Tidal currents can sweep even the strongest swimmer out to sea and rivers can have hidden currents that can trap the unwary. Water will also cool the body 25 times faster than air, so watch what you are doing. You should never enter any body of water until you are aware of what is under the water. This is particularly important with urban ponds and the like, where all manner of debris can litter the pond bottom. Footwear is always recommended in such locations.
As a rule, for skinny dipping, I always wear my sports sandals to protect my feet from rubbish and sharp rocks and never get out of my depth. Generally, if my feet cannot touch bottom, I don't enter the water. Just my own preference.
