I too am looking for a man to seduce my wife. I was trying to arrange a meet-up (un-beknown to her) where the guy would run into her at a local casino and attempt to "pick her up". while she was there by herself. Her being at the casino and getting picked up is a very strong theme in our fantasy play as she often goes there by herself. It's very difficult a to arrange as she doesn't have a set schedule and often times lets me know she's going with only a days' notice, but I've been very diligent and managed to arrange this four times with four separate guys, who have all bailed at the last minute.
Long story short; Be aware that there are many men who say they want to try, but few who will follow through.
