I'm going to admit something here that I might get backlash for. I'm sure this goes both ways.
Every guy is different and has his own stimuli. Some like soft, some like friction, some like kissing massage, etc. I react to his body language and or verbalization to cater to his particular needs. Every once in a while I run into a very quiet, completely non-reactive client. Since I don't like to rush anyone, I react to a gentleman's body language or "moans". If he is totally quiet, no body reactions then suddenly asks me to stop because he is about to cum...I get stumped.
It's so hard to move forward at this point. I realize I am supposed to be the "pro" here, but I am not psychic either. I am sure some hobbyists have occassionaly had similar reactions during DATY.
I welcome opinions and hope someone may find this informative from a provider's POV. Any quiet hobbyists have feedback for me?
