When we met and got married we were both students.
We agreed, house is cleaned once per week on Saturday, split the cooking 50/50
We chose which bits we wanted to clean, eg I did kitchen, he did bathroom, and so on. That way I got up, did my cleaning and he got up and did his. As long is it was done by sat pm we had a deal.
Now I am SAHP, and I do the cleaning, but as I take on more part time work, dh is taking on more cleaning, at the moment, I organise it - I will say upstairs needs hoovering for example, but as the balance to 50/50 work returns, so will the balance to 50/50 jobs.
Dh has never expected me to do his cleaning, he is very aware that if the loo id dirty, then he should clean it and not 'wait for me to do it' he has never seen it as 'my' job.
I think my brothers are the same,
Maybe it is how we bring up men, so my question is, what are we modelling to our sons?
