I can't speak for anyone else but it's kinda rare for me.
Even when I was an active JW, I knew that most of the "friends" weren't real or close. There were a few that I got along with better than most anyone else, but there was hardly anyone that I would confide in my secrets, fears or dreams.
Even the people I considered "best friends" were not that close. We may have spent hours and hours together and shared tons of experiences together, but there was always some barrier between us. I can't explain it. Sometimes I think it was the JW religion and the fear and guilt that came with being a JW. We had to hide our alter ego from those that we knew from the hall and we hid our JW life from people we knew from school or elsewhere.
Now that I'm out, I still find it hard to make close friends. I've made friends with a couple of guys with similar interests and I can tell that they're trying hard to include me in their circle of friends. But I've been a loner for so long, I've gotten used to my own company and it's hard for me to allow people to show too much friendship to me. They'll expect the same in return and I'm not sure I can return it in kind as well as I received it.
