I've never had kids, I'm petite, and I have never actually needed lube. Including my first time. The only time I've needed lube was when my bf wanted a quickie behind his parents house and I was not turned on in the least. The birth control must have enabled you to need lube.
Once your body is producing its own lubricants you'll find that lube doesn't make sex feel better, it actually makes it quite easy to not feel anything at all!
