on dental dam for DATY .   i agree with last comment .. one time ( and so far only one time)  a girl pulled out a dental dam as my mouth slid down her body .. i am WTF ..   i tried doing that for a minute .... i didnt see the point for either one of us.  

i would rather a lady just said, i am not comfortable with a guy doing that  (DATY) .. that i would totally respect.    after all how would i feel about countless strange women i just met giving me BBBJ ......  ok maybe that was a stupid question  LOL    but seriously i can understand how that activity could be very personal for a girl, even more so that intercourse itself.
