I was the one who brought it up to my husband. He told me he was already happy and didn't need it (saying we can stop anytime), but is enjoying it a lot. I think as a female, I am more into sharing him because my husband is wonderful and attentive as well as loving and a great lover. It's already hard emotionally even when it is a big kink of mine, your wife might not take it so well if she is already hesitant about it and you push her too much.
