M.,
You should really take a serious look at Natural Family Planning. Modern methods are very accurate, as good at preventing pregnancy as artificial methods, and they do not have all the health risks of the artificial methods. Also, NFP is very good for a marriage, for lots of reasons that I won't go into right now, for brevity sake. Condoms are not very effective, and let's face it--they're disgusting. Vasectomy has very real health risks for you, as well as for your husband. Sexual relations between husband and wife without barriers of any kind is wonderful. NFP makes it possible while minimizing the chance of pregnancy. Check out www.ccli.org for more information, or I'd be glad to talk with you or e-mail you personally, if you like.
Blessings,
M.
