I have enjoyed GS play a number of times with several different Dommes who also seemed to enjoy engaging in GS. These experiences have usually been between what I think are two extremes. Dommes usually made a point of telling me that they had been drinking water prior to and during the session and that I should have no problem with their "nectar". The opposite was with a Domme what I got to know pretty well and was always coming up with ways to surprise me by taking any session request I might make to another level. In response to my GS request she let me know that she had coffee and asparagus earlier that day for lunch and that no matter how difficult it might for me be she expected me to drink every drop.
GS play was always very erotic to me, though sometimes the cleanup afterward was not nearly as sexy!
