Frustrated after sex

Me and my fiancé have a active sex life but lately I have been really frustrated that almost every time We have sex he gets me close and then he cums and just rolls over. I get very annoyed that he keeps getting the pleasure out of this and I am just left there with nothing and it's just not a big deal to him. I've tried to talk to him and all he says is well sorry. I wish he could last a bit longer sometimes and it wasn't all just about him. Tips ladies? I want to enjoy sex again.
