I'd like to suggest you go pick up the book "The Five Love Languages". It's inexpensive...and a very quick read. I recommend this because you mention there is no emotional connection for you...and I can understand how that wouldn't help your sex drive at all.
My guess is...the two of you don't speak each others Love Languages...I can guarantee your H doesn't if you feel no emotional connection to him. Chances are...you aren't speaking his either, albeit unknowingly.
Read the book...identify your own primary and secondary love languages...then figure out things that your H can do that would fit into those categories and communicate them to him. There's even a quiz in the back that you could take together with you H (in a fun way) and figure out what his Love Languages are....make sure to ask him what YOU can do to make sure you speak his languages as well.
This may sound like a bunch of hooey LOL...but speaking each others love languages goes a long way towards fostering that emotional connection you are missing...which in turn will help spark your willingness for sex as well.
As for the schedule you two keep...I would absolutely schedule in some quality time for the two of you, a date night once a week...or even once every two weeks. You make appointments for other important things in your lives...you need to recognize that you both need to make appointments for time to foster your relationships between each other as well.
