Is this normal?

I have been married for almost 4 years to my 24 year old husband. When we have sex, he complains that I make it all about me.I love foreplay, and like to have it for a long time. He doesn't, so he isn't happy when we do. My guy likes me to tell him sex stories about him and me and being with other girls, sometimes more than one. He says that he loves me and wants to only be with me, but it's hard for me to understand this. He cums a lot faster and harder with the stories of other girls, then if the story were to be about me and him only. Why is this? I don't feel comfotable telling him stories about other girls, but its causing a major problem between us, and I just don't know what to do. Should I bite my lip and make him happy?
