Unsatisfied

I don't know how to tell my husband that out sex life is not pleasing me... We've been together for 16 years and the pass year has been a blah! It's like every time we have sex he never try's to please me .. I'm so bored with it to the point were I don't even want to engage in it which sucks cause I want another bby! I just don't know if I should just blurt it out to him. Frustrated! Mentally and sexually..
