Being nude was not something that was forced on my sister and me, or was part of our family lifestyle, but we came about doing this naturally as pre-teen girls home alone because school got done a few hours before our folks came home from work.
To go back a bit further than that, when we were in single digit ages, mom would administer enemas to us when dad was out of the house for an extended period of time (e.g., golfing, going to a sporting event, bowling, whatever). Mom would just tell us to undress, come into the bathroom, and we would get our enemas and rinses, then shower and get on with the rest of the day or evening.
If she knew dad would not be home for a while, she'd let us romp about the house in what she called 'in the all-together.' She kept an eye out for Dad's car (sometimes he would call ahead that he was going to be leaving the golf course or lanes) ... she'd warned us when he was coming up the drive, and we had plenty of time to get dressed. It was our threesome secret. It always felt so good to be unencumbered by clothing.
About age 10 or so, mom taught us to self-administer ... when we were home alone, we'd turn this into a game ... shed our clothing and cavort around the house nude ... do our homework that way, even do some housework mom assigned.
It felt so good ... but this was totally private thing ... no friends knew and we never went naked out-of-doors.
we did this through our teens ... never losing the comfort of being without clothing.
In college, we had the opportunity to go skinny dipping a couple times, but it just wasn't the same ... by our junior year, we opted out of the skinny dipping sessions.
Now my sister and I are married ... when our husbands get together for hunting, sports events and other all-day activities, we revert back to our high school days ... but again, this was a totally private thing. My hubby and i love to go nude when we're home, and because of the location of our residence, even out-of-doors. and we both love it.
My sister says she loves to visit ... especially when her husband and mine take off for the day because her hubby is just not into private nudity like she and I are.
As you can see, we just evolved into the 'clothes-less' society function of our own ... we got comfortable with it at a young age and simply have no intentions of curtailing our activities. My hubby and I enjoy it ... no we don't 'do it' everytime we're nude, but if we get the urge, there's no preparation time necessary.
With my sister and I, I'll tell you right now, we're not lesbians by any stretch of the imagination, although we're still into the enema thing, and we do shower together, swim au naturel in our pool during the summer and even lounge in the sun together (weather permitting) ... we're just two All American gals, you might say, and we're continuing to enjoy life as Adam and Eve did ... oh, why did they mess up. It would have been so much easier for everyone. lol.
