I feel like my wife would love to have a bigger sex life including adding others but at times she shuts down if I being surf up and other times seems Go go along with it. Any advice for a shy wife and how to introduce other topics ?
It is a question millions of men have asked, and there is no right answer. Very few women are going to be into that. Maybe 10% - maybe. Most women are not going to take that well. And many will take this interest of wanting to add people, as you are not satisfied with them. Women take sex way more personal than we do. Also - she may seem open about it sometimes, because she is just being agreeable.
