Of geez, here goes nothing.Most of you may have figured out by now, but for those who hadn't and are still confused (and just really, really gotta know), typically, a dental dam is associated with safe sex for lesbians during cunnilingus for the prevention of transmitting STDs. It is thick (thereby hampering pleasure-ability), doesn't taste good (again...)and there is controversy about its effectiveness. Saran wrap is actually a more highly chosen safe sex barrier in this situation, from my experience and that of other lesbians I know. Whether dental dams are used by heterosexual couples, I don't know, although I've wondered.
I know this is probably MUCH more than anyone here ever wanted, needed or hoped to hear about dental dams at the mudcat. I apologize if I have offended any readers.
