Sex please?

37+1 and not in a hurry to get baby out, but definitely don't want to go late. I made the mistake of telling hubby that baby is at 0, so now he is freaking out about sex. Like, totally not an option. 
A- I want to have that option in case we start going overdue, and B- a girl has needs, and the 6 weeks after birth are going to be sooooo difficult. Any ideas on how to ease hubby's mind and not feel totally rejected?
