The same was going in the congregation I first attended when I joined WT in my early 20s, was told through my Bible study that witnesses don't have sex before marriage, drunkenness is forbidden. Then I started getting to know and hanging around with the young JW crowd, first thing I remember saying to myself after spending my first weekends with them as a new JW, was that these people aren't any different, they are all heavily drinking and swearing. I was surprised 😮. Then as time went by, and getting to know the young ones better, I started hearing about who had done what to who sexually, even out country witnessing, I even walked in on my first witness girlfriend at it with a single brother who had only moved into our congregation a week earlier. I know a lot more that never got reported, then there were those who did get their names mentioned (reproved) at the meetings. Thinking back, there was a high percentage doing these things.
I did type up more real life experiences in this post, but after reading them, I decided to delete them, it sounded like it could be made up, even though it wasn't.
