What is the best to do? me getting my tunes tied or my husband getting a vasectomy? what are the benefits, cost, and easier to reverse?

You can freeze both eggs and sperm if you have a change in mind later (you are only 24!) And you might get divorced and other changes occur in your and his life and economic circumstances! There is no rush to decide today!
