Would it be unreasonable to suggest a vasectomy to my husband?

My husband has decided that children are not in our future. (Long story, not going into it here.)

I’ve been taking Yaz for about 2 years since that decision. At the time, it was the simplest solution. While Yaz has done good things for my skin, I’m not sure I want to continue taking any medication that isn’t medically necessary.

I’m considering suggesting that he get a vasectomy so that I can stop taking birth control. As it was his decision to not have children, is it unreasonable to suggest that now he can be responsible for birth control? As well, if anyone has suggestions regarding how to have this conversation, please add those to your response.
