Awesome! Bout time. It's not just about responsibility, but agency as well. Both people want a baby? Great! Outside of that, it's really up to the women whether they have a child or not in the case of an unplanned pregnancy. If the woman does not, she has the option of abortion (regardless on your stand, it's a reality; i prefer responsibile birth control), which is the last option; man has no real say. Same if she wants to keep it. The man is on the hook one way or another with no real choice. Male birth control would give men more agency in that decision. It will also help reduce unwanted pregnancies and consequently abortions.
