Pregnancy

My friend and I are both adults in long term relationships with men we love. Our men both want babies and have been vocal about it to an extent and her and I both want children. We hung out today and decided we both were wanting to TTC but we don't want to pressure our men and bring it up so we want to just do our things, have unprotected sex and see what happens. Is that wrong to not tell our guys we want to TTC even though they want kids too?
