Someone in the group recently referred to loving rim jobs. I (F) would like to do this but with some kind of "barrier" like Saran Wrap because no matter how clean, it still smells too funky to not remove me from the mood. So, rim job lovers, (1) Would a barrier ruin the experience? (2) if it would still be nice for the receiver with a barrier, any suggestions? (3) if a barrier is a problem, alternatives?
