It goes way back before that even. Some of the raunchiest films came from the very early 1900s. 5he history Channel I think it was, and a show on it,, and it was filthy.. but really, sexual immorality goes back to even the beginning of the world, where rapes did happen, where in. Noah’s time, 5hings were totally out of control. Even angels, fallen, were having relations with women it is said. Sexual immorality is nothing new, and was always bad. People just ignore how bad it really is
It has been around a long time to be certain. Sodom got its reputation from something.
The difference is that the rot has primarily been confined to certain classes. With mass media and now social media, it has penetrated deep into the common culture.
