Virginity is certainly not specific to JWs, although there are a lot of unusually old virgins within the JW ranks. Maybe that would be a good topic for a new thread - "What is the oldest age of a JW virgin that you know of?"
Years ago, I worked with a guy who appeared to me to be a virgin in his early 30s. I had a casual conversation with him one day and caught him using some Dub buzzwords, so I asked him if he was a JW. The answer? Yes. That same guy tried to pick up on the hottest lady in our office, one who was interested in wild, heavy metal type guys, rather than nerds like the virgin who tried to pick her up. The result was disastrous for him, as she told everyone in our office how he drove her home from work but intentionally passed the freeway offramp that she asked him to get off at. The poor guy had no chance! How embarrassing.
Peace.
