I need advice...

Abigail
I've been in a committed relationship for about a year and four months. We're very happy together and I really do love him. 
But there's one significant problem. 
I feel like he uses me, sexually. 
It's always a give but don't receive process for foreplay, even when I asks. He'll say something like 'I'm not feeling it.' And he always asks for things like oral, but then he's done with sexual contact and wants to be lovey-dovey. I don't know what to do! Do you  guys think I'm being used or is this normal?
