A question for the lesbians about dental dams

So, last night in hanging out with a couple of my friends, we got on the topic of the female condom and how useless it was, and one of my friends mentioned how useless and unused the dental dams are. Now, I don’t have a huge store of lesbian friends to make a proper poll myself, but the ones I do know ALWAYS use either dental dams or ceran wrap if they’re ever having sex with someone that 1) they don’t know all that well, or 2) have knowledge that they’ve had sex with a man (some always, some if it’s just been recently).
I held my tongue, but I’m curious, for all the lesbians out there on the board, who uses dental dams/ceran wrap?
