I am 21 and have two kids my husband wants a vasectomy but I want more kids HELP?

You should talk to your husband. You guys should come to some kind of agreement, such as, just one more child, use condoms or some other form of pretection until you both are ready to have another child, but don't let him get a vasectomy because if he does you guys will not be able to change your minds.

Marital therapy of some kind (eg.professional, spiritual) seems essential since you are talking about such basic deep human drives not coming to an agreement here could doom the relationship or cause psychological problems
