The best providers are able to tune into something they find appealing about their clients and connect with them. It may be a physical attribute (pretty face, nice smile, great ass) or a personality trait (kindness, humor, it factor).
At the risk of sounding immodest, I have a good face, a great ass and I’m really funny. I’m also quite skilled in bed. Most guys connect into one of those assets and build from there.
I also find more experienced providers are generally better at making this connection.
