Need actual advice on some sexual problems.

Here it goes lady's. My fiancee and I have been together for 3 years. We are getting married next June.Let me just start out saying I'm 32 He's 42. In the beginning of our relationship fore play was both ways. Now it's mostly one sided where he gets pleasured. Almost every single time while I'm not. So when we start to have sex he's done before I really get going. I get frustrated. He wants sucked off every single time. I'm like no because we are having problems now. Like I'm gonna get you off where I'm not. I have brought it up many times if we please each other then the ending just might be more enjoyable to us both. 9 out of 10 times I almost get him sucked off while I'm just waiting he just lays there.
