I don't think so. The hippie movement was a reaction to extremely stiff social norms that are not at all applicable today. We have a lot to thank them for their disobedience to that.
Today, outside of your family and maybe some friends nobody really cares about your drug use or sex life. There are some prohibitions by law, but I doubt these are too relevant.
I often ask myself from which cult people have escaped or how old they are if they indict current society of being restrictive or even suppressing in some way. Frankly, I don't see that at all. Maybe it is a wish, since that would mean that society cares at least somehow.
Maybe I am lucky, but I don't really see restrictive norms anywhere. You see a lot of people not caring though. The internet is no reference here. You can save a puppy from its inevitable demise and certainly someone will be deeply offended by your actions.
> If everybody had sex today tomorrow would be awesome [...]
Always a better tomorrow... but I highly doubt that. Some might crave sex and some might crave intimacy. Anyone bragging in the office about hook ups would be suspected to seeking confirmation. The same is true for males since quite some time. Cultural suppression? I don't think so. Because if you would do that, I think the repercussions would be almost negligible. Some will judge you, but that will happen if you wear the same pants twice. Maybe not a bad choice of fetish, but certainly no fight for more freedom.
