I'm in my early 30s and DH in his early 40s. Our sex drives used to be mostly well matched but if anyone wanted sex more, it was usually me!
Over the last few years I've had two kids, a heart problem, hormonal imbalances - along with all the stress that everyone else has had going on - this, understandably has put a dampener on my sex drive.
We have sex now about twice a week, which I think is OK. I literally have no sex drive at the minute
so sex for me is a big deal and it involved a hell of a lot of acting. If it was all up to what I wanted we'd probably never have sex!
I've had this chat with DH, even my heart nurse has had a chat with him about how my meds and hormones can mess with my "urges" and he nods in all the right places BUT he's constantly on at me for more sex 
He won't ever just go and jerk off either, be even wants me to be a part of that, which I find bizarre, not that he finds it a turn on BUT he NEVER does it alone! He's always touching me, squeezing my bum and boobs. He constantly makes lewd comments when we are alone. It's driving me nuts! I'm getting to the point where just him touching me is making me want to tell him to piss off.
