How to proceed
I (48 M) have brought up swinging and hotwifing to my wife (40F) during intimate time over the past 2 years or so and she has always shut it down. We use toys and a simulated MFM. She always enjoy it during but afterwards she will say she could never do that and only wants me. She is shy and self conscious since our child was born. During a recent beach vacation she after seeing how some of the women were dressed or lack there of on the beach she said she doesn't feel bad about her looks. One light we were sitting on the balcony looking out at the beach and she said look those people are going skinny dipping in the ocean. She ran and got the binoculars and was watching them. She watched them for probably 30 minutes until they got dressed. I was standing beside her and started playing with her boobs and pulled her shirt up, she immediately pulled it down and said no. I said come on let me her response was people will see. I said good and removed her top and continued playing with her boobs. We end up in the bedroom where I go down on her and her pussy is dripping wet. I started talking about the people on the beach and said it looks like you liked watching and she said yes. I proceeded to say what if they were having sex would you watch and she said yes she would watch with me. I told her I liked that and was up for trying new things. She hasn't brought this up since and I am not sure how to proceed.
