Sensation feels way better when you make him wet. Try to generate lots of saliva and use your hands to spread it all over the head and shaft. If you need help generating enough moisture, suck on a mint to get your saliva glands going.
If you are not using latex condoms, you can add to the lubrication with almond or coconut oil. Both taste great and can add a lot of slip and slide. If you will be using condoms later, stick with saliva or a water based lubricant.
