It's not a matter of opinion and it's not open to interpretation. It is not a matter of what feels right for you. Being promiscuous is wrong, period. The purpose of sex is for bonding, and if the other person isn't the one that you want to be with, you have no business having sex with them. When you have sex, there is an exchange of energy that occurs. If you have sex with someone who you don't have that kind of connection with, it damages you. Sex is powerful, and it can also be dangerous if done irresponsibly. These days, there's way too much promiscuity. That's wrong. Just because something feels pleasant, it doesn't make it right to do it just because you feel like it. We're not just animals, we're spiritual too. We have animal desires and instincts, but they must be regulated by our spiritual side and channeled for the right purpose. If you want to live purely as animals, then casual sex would be fine, just as it is with the other animals. But if you want to live in civilization and if you want to be a complete human being, having casual sex is wrong. I judge promiscuous people as being immoral. There is such a thing as objective right and wrong, and promiscuity is wrong.
