Sexually Frustrated

My boyfriend has been so tired lately from his new job that we have no sex life...only time I can get him to agree on something is if I give him oral..I don't get it in return nor do we have sex after... I'm lucky if I get it once a week..and because it's so rare now, it goes very quickly...I know he's not cheating and he shows me affection in other ways like hugs, kisses, and spooning.
