Woo him by taking him out to a fancy dinner and a romantic stroll.
Think of all the times he takes you out and works hard to impress you. He will enjoy taking a backseat and proudly watch you take over.
Have a sense of humour about sex.. It will help relieve the intensity.
Trying new moves out may not work out right away. So just laugh it off and try again. Another thing to remember is if he gets excited rather quickly he doesn’t want your pity. A massage or more kissing may be what’s needed to get him back on the saddle.
