Before meeting with your favorite or any escort, tell him that it really turns you on to make him cum. If that’s of no interest to him or he can’t guarantee such a result, a good guy will tell you. Then, when you’re kissing and engaged in foreplay, look him in the eye and ask him what really turns him on - what can you do to help make a memorable cumming experience for him? You may be surprised to hear that he may like his nipple licked, or his balls sucked, or your finger up his ass. That’s the approach I’ve taken and I think for the most part escorts have appreciated my interest in them, rather than entirely about myself. This is best for more than a one hour session.
