Scarcity of sex in marriage

So my hubby and I have been together for about 9-10 yrs and we are recent newlyweds going into yr 2 in feb. it seems that his sex drive has gone way down since we got married. It wasn’t all that high when we were only dating before marriage but now it’s worse there are months of dry spells and I’ve already told him that we have to figure out what the issue is. My sex drive is pretty high like I always want it. But he doesn’t and he gets lazy and won’t shower for a day or two which i told him had to change. All he’s said is that it’s not me and that he gets lazy when he gets home from work. We have different work schedules. Idk what to do I’m worried that our intimacy is going to die but it’s not like we don’t cuddle and he’s affectionate but it doesn’t lead to sex. It’s taking a toll on my self esteem. Sorry I guess I just needed to vent and see if any one has experienced this. We are both in our early 30’s.
