hey. I am a huge fan of oral sex. But anyway, dental dams are an interesting change. They add a different feel. As far a saftey goes I really don't know. I wouldn't want to use a dental dam all the time. That would be no fun now would it. I can't really be of much help here. I am glad things are working for you. It sounds like a complicated situation but if it works for all parties involved great. I'm glad he's a nice guy.
