Great question and answers!
I've been learning with age and experience here that I try hard to communicate as much as possible in a loving and caring way. My nipples and clit are very sensitive so I let them know that or whisper it when the time is right before they twist or bite my nipple too hard and sometimes with DATY my body language sends a message, so if I'm backing away or moving my body a certain way I just ohhh easy or something to give a clue.
And when I start my bj I always ask them to pleas let me know how they like it, fast slow, are hands ok?,....etc.....its so hard when your on a first visit and we've got no clue what you love . Also some guys just are so still and aren't verbal and I have no idea if I'm on the right track or not!
So communicate , communicate and I've found my play dates go so much better when I know how to rock your world!!
