Husband won't touch me

I'm almost 20 weeks pregnant. My sex drive was non existent up until about a week or two ago. Now that I have a sex drive he doesn't want any...

Says that me showing makes him more aware there is another human inside there and it makes it weird for him...

Any advice?? Am I really not going to get any for the rest of my pregnancy?? And then some?? Cause I know after baby is here I'm not gonna want it near as much due to exhaustion...
