It is perfectly legal to break someone's heart and make them feel worthless or used.
Likewise, a person's private life should remain their own business.
Though here is the question. Do we really want to live in a society that condones "anything goes"? I mean, private life or not, is it really beneficial in the long run for everyone to keep chanting these trendy buzz terms such as "monogamy isn't for everyone"? Is that the standard under which we want to raise our children when we have them? "Go ahead honey, go out there and do what you want, so long as it isn't murder or doesn't harm anyone visibly while they are in your line of sight, then feel free to do it. I mean isn't that how sweat shops operate? Modern day slavery... out of sight out of mind.
I don't care who you are, what political affiliation you have, how liberal and innovative you think your ideas are, and regardless if you adhere to Gnosticism, or insist upon a A-Gnostic reality; you are going to teach your child boundaries in order that they do not do something that is going to immediately or eventually bring physical or emotional harm to them selves or others. It is not in the best interest of their health, the health of those they interact with and try to make friends with, and it certainly does not help to make the parent's life any easier.
Granted, we do have a lot of adult children posing as parents who do very little in the way of raising their children in knowledge, compassion, and wisdom, but for those parents who see beyond their own self wants, this is the way of things.
Now as for me, if two beautiful women offered to take me home, one sitting on my face while the other...
...well you get the idea.
Well do you really think for a moment that that would not be tempting to me? Do you not think that that would not provoke some INTENSE sexual urges within me? I could jump on the band wagon and say,"hey why not, it's only pleasure?", but at what cost?
If I built a reputation of hanging around sleazy nymphs as such, would I really get the time or day with a lady who is refined, educated, and aspires to care about others as much as she does her self? Would such activities help me to be content with the one I love? Would they not have any effect on her (presuming I was in a tender relationship), would I not be hurt if my dearest lady friend went out and had a quickie with a couple of guys? Would conducting my self in front of my proverbial kids be beneficial to them? Having multiple women running around the house and no central mother, or seeing parents who will do what ever they can to find pleasure?
Mind you, some people (like some of my friends) are more about this. They are not very good when it comes to expressing or dealing with their emotions, and they are certainly not very good at dealing with or handling other people's emotions. Generally they are miserable and like to fill the void with booze, pills, sex, and well what ever gets those endorphins flowing, if not for a little while. (Not that I don't enjoy my herb, but it's not my only source for joy).
They were not brought up with discipline, or wisdom, as with most of them, their parents split when they were young, they were not shown much affection growing up, and this and that. Basically they just repeat what they saw growing up and never bothered to try not to repeat it for what ever reason.
For them, you ask them what is wrong with this picture of open relationships and what not, and they say nothing. They are already miserable and don't really know a better life one way or the other, nor do they know how to keep someone's trust, or to put their feelings or wants on the back burner when a friend is in need or what have you. So for them, they will say, everyone should get all the sex while they can, look at me, ain't hurt me any!
Though again, if you ask a child addicted to candy if they would like to eat candy for the rest of their lives, they probably will say yes, that they would replace their daily diet with it and never eat fruit or veggies again...
Once more, because they have not lived long enough to experience how sick that candy will make them, or how much it will shorten their life.
Anyhow, I'm tired of typing, dunno why I have to explain the obvious in such extreme detail anyhow? Bottom line, our society is sick, selfish, and short sighted when it comes to a lot of the finer things in life.
