What did he say to your requests for foreplay and a longer duration?
Have you ever explicitly told him that the reason you do not want more sex is that you don't enjoy it with him?
Also, how much are you willing to compromise to find a lovemaking style that works for both of you? That is, he will probably never get that much out of tender-type sex but I would imagine he could meet you in the middle if you are willing to try that.
