Carla,
First, it is great that your new guy really seems to want to please you! But...being a
new guy, it can be really hard to just open up and tell him right away what pleases you. That is sometimes part of the fun of discovery!
Every person is different and consequently, what may have really pleased you in a former relationship may not be the same in a new one. It takes time to develop the trust where full sexual communication can feel comfortable.
Maybe let him know that while you do aim to please, it might take awhile to fully cut loose! Good luck!
