I think its best and probably vital to incorporate your wife. I know mine was a bit like wtf at first however now seeing how much I enjoy it we enjoy using it together for fun. You also need to tell her that’s its not a wife replacement like how they usually think at first. To them they think well why would you want this?? If your wife has seen or knows that you jerkoff from time to time then she shouldn’t have a problem with it. If that stuff is a no no then you guys obviously have other issues to work out before you try to introduce this monster cum thirsty machine lol. Also they have the payment plan that helps ease the burden. Thats what I did. Basically you have to know your wife and work it in based on that IMO. Is it for every couple I don’t know..
good luck and keep us posted!
