Why has my husband changed sexually?

sex with him used to be get until recently. He is no more interested in foreplay. As soon as he gets hard he just rubs oil on his manhood and then forces me to have sex. He doesn't kiss nor romance me enough to get me wet. I'm so bored with him, I travelled for two weeks and got back last night, we have been talking about sex whiles I was away so I thought it was gonna be great but it was just the same.... I know he loves me very much, I've talked to him about this but he is not making an effort to change. What should I do? As soon as he cums, he sleeps right away.... For months now I haven't been satisfied at all...
