Well, even if that was 100% true of you, there would still be your guy to consider–it would be very, very unusual if both of you were like that.
This transition is typical enough that C.S. Lewis talks about it in the Eros chapter of The Four Loves (great book, by the way).
What’s happened in our family is that in the initial courtship/newlywed phase, there really wasn’t a lot of work at home–it was just the two of us in a small apartment. Plus, not being parents, even though our income was small, there was proportionately a lot of disposable income.
As the family grows and the home itself gets bigger and the couple becomes homeowners, the base level of work that needs to happen for basic survival rises and rises–it’s not just a question of 10-20 minutes of chores a day anymore. Little babies, for example, are known to eat every two hours, round the clock, week after week. And that’s just one thing. And each child or life transition (a move, a new job) can add to the load. Plus, with each additional child, the slice of the pie available for mom and dad fun gets smaller and smaller. (I believe I last went and saw a movie with my husband nearly two years ago.) “Date night” is prohibitively expensive for parents, even if it’s just fast food and a movie–that’s a $50 night out once you pay a sitter.
Both my husband and I do way, way more housework and childcare work day-to-day than we did in our let-me-do-all-the-things-for-you phase. That’s why additional spousal requests are often resented in Step 2–because each member of the couple is already working REALLY hard, and they may each feel like they are already doing all the things, and their spouse is being selfish by imposing more.
And back to the main topic of the thread, that’s why the virginity mania is so weird and stupid–the obstacles of young parenthood are huge, virgin bride or not a virgin bride–and being a virgin bride will not keep your baby from colic or clear up a tummy bug faster or make a dental bill cost less.
