Exhibitionist couples and social nudism
Having been to both clothing-optional and nude-obligatory resorts/venues/events - the latter almost exclusively in the past few years - I have noticed a difference in behaviors between the two. Specifically, nude-obligatory attendees in general being more uninhibited than their clothing-optional counterparts. My theory on this is because people at the nude-obligatory venue do not have an easy option of covering up, should they feel a bit self-conscious or "awkward" in social situations. So unless they choose to sit in the back of the pool area and not move all day, they are going to have to accept being seen "completely exposed"; or just leave/not come back. Added to this the fact that they are going to be surrounded by uninhibited folks; which for women can often lead to a "well she's comfortable that way, so I guess it's ok" motivational factor; which can lead to increased confidence being seen "exposed."
As a result, exhibitionist couples can become virtually indistinguishable from couples that might not consider themselves "exhibitionists." A woman sitting by the pool legs open - or practicing group naked Yoga by the pool area - specifically to be seen "wide open", would just be one of several other ladies doing exactly the same, albeit without the same intention.
But the question one might ask is: "are the couples - that are not intently exhibitionistic - still being exhibitionists anyway as a result of their lack of inhibition?" This is where people have a lot of different opinions on what constitutes exhibitionism.
My take on it is that there are "levels" to exhibitionism. For me, there are certainly times where I embrace standing in front of a lounging friend; and them getting a full view of my cock dangling as they look up at me. Same for my wife, who at times will "present" people with unobstructed open-legged views of her bald vulva while interacting with them. During those moments, with both if us being bald and having our "privates" displayed very "publicly", I'm sure an onlooker would think we're an exhibitionist couple. And at the time, we probably are. We're not always willfully completely exposed to other people; but we certainly are not shy when it happens. Call it "exhibitionist-lite."
A lot of nudists are afraid to be perceived as exhibitionists. A lot less so in "nude-obligatory" settings. It's been made into a "dirty word"; but IMHO it can actually be beneficial - in doses. My wife enjoys seeing other women looking at my cock and being responsive to it; and I equally quite enjoy the glances my wife gets when she's interacting with her pussy in full view. It keeps our intimacy vibrant.
