I'd be very interested to chat. I absolutely don't want to cause anybody any problems but would like to genuinely have a fun experiment with a couple. Probably like you, I wouldn't want to distress your wife but do understand both your excitement and concerns.
Rather like your forum discussion, an acquaintance who studied yoga gave my wife a massage and like you, I would have loved him to take her there and then whilst I watched. She was very wet afterwards and clearly would have liked to receive him. Unfortunately now she doesn't do sex any more but it remains a strong interest for me. It would be such fun to have a hotel meeting to see if we got along.
Let me know if you would like to chat further.
Regards
A xx
