Is your average elder not married? or is it just because JW's aren't allowed to do anything fun?
Most but not all are married - and no, they are never allowed to do anything fun. Talking about this at meetings is as much fun as they get.
I think that as bad as it is to be talking this kind of graphic BS in church, worse is the fact that it is actually said right in front of kids of every age from babies on up.
I have seen graphic descriptions of such things as oral sex presented which were written by the watchtower society, and they ordered them to be read word for word during the friday night service meeting. That was in the early 1970s, so it may not still be going on now.
