What does a dental dam feel like when getting rimmed? I want to start rimming my boyfriend and was wondering if he would find it pleasurable if I used as dental dam for safety I've done some light rimming on him and he really loved it, and being quite fond of him I would like to rim him more - he has a beautiful *** and it just feels right. I am a top and have never had one used on me so I have no idea what it would feel like, although I have been rimmed without a dental dam and I loved it. Any tips on making use of a dental dam more pleasurable.
