Sexless marriage

I have struggled with sex for about 2 years and 6 months. I had sex with my husband about 15 times in that time frame give or take. I had my Son in aug of 2021 and three months later my Daughter was diagnosed with type 1 diabetes. The first 3 months after the diagnosis were hard.

I almost lost my job and trying to keep her blood sugar in control was hard. I work a 9-5 job, take care of the kids, cook, and clean the house. I do it all. My husband is a stay-at-home dad since we don't have people able to watch our kids and there is no daycare in town. I get crap from my coworkers about trying to make my husband do more but I have tried talking to him about helping out more and he thinks things are fine. I am constantly overwhelmed and stressed with trying to be enough at home and work but I feel like I fall short all the time.

I want to start trying for our last kid soon since that has always been the plan. My husband will most of the time help if I ask but I feel that I shouldn't have to ask since he is home doing the bare minimum for the kids like changing diapers, feeding lunch or snack, putting on cartoons, and maybe playing with them a little. The rest of the time he is watching YouTube or sleeping basically.

Occasionally he will get wild hair and do some dishes or fold laundry but it's also if I haven't done it for a few days and it's gotten "bad." But he is an absolute horn dog and would have sex 2 to 3 times a day if it were up to him and I barely have the energy to get the house and kids taken care of.

I am just wondering if there is a way for me to become more sexual again. I want to be a good wife and do those things cause I do enjoy it but getting into the mood for it is so hard when all I can thing of are the things I need to be doing.

Sorry for the long post. Please no negative comments I already get so much crap from my coworkers that I don't like to ask for advice.
