Let me know which direction would be useful to you.

Do not go to a "lifestyle" or swingers resort. Look for organizations affiliated with the American Association for Nude Recreation (AANR) or The Naturist Society (TNS) in the US, or INF/FNI internationally. These venues have strict codes of conduct regarding photography, ogling, and sexual behavior.

When you remove clothing, you remove the primary signifiers of consumer culture. You cannot tell who is rich (a diamond ring looks silly next to a sunburned finger) or who is fashionable. You are left with the raw human animal.
