EW! I hate when that happens! I'm not a JW, but my mother comes from a family of JW's, and I've never heard anything like what you've said here. I really can only guess that this guy was a little bit on the sick side. From the stuff I've heard with my mother's side, JW's are pretty much all about not having fun... so I can't see them being too much into anything pleasureful.
