Everybody is different in their specific requirements and required outcomes. For us, my wife would trust me to find the right guy. That wasn't too difficult knowing her preferences, but finding the guy to fit that requirement was more challenging. We used the Web site, Adultfriendfinder and I put in the precise details of the sort of guy that would fit both our needs.
We found this process very enjoyable and part of the foreplay. When I found one or two potentials, I would present the profiles to my wife to choose for the next stage. I would make contact and try and assess if he was the sort of guy that would totally respect my wife and her requirements and my preferences too.
This would lead to a great evening. This method never let us down.
