My (36M) shy/vanilla wife(36F) googled fantasies and told me she’s into roleplay… and partner swapping

We've been married for 10 years. Yesterday afternoon I asked my wife about her sexual fantasies. She said she doesn’t have any (she’s pretty shy and vanilla in that way).

So I asked her to google some and pick whatever interested her, then share it with me at night.

Later at night when we were in bed I asked again. She said she had read a bunch and three things caught her attention:

1. Roleplaying with her partner (doctor/patient, air hostess/passenger, that kind of thing)

2. Threesome & foursome

3. Partner swap

I asked which one she actually liked. She said she liked the roleplaying idea and definitely wants us to try it. I said okay and kissed her.

Then I asked about the other two. She said threesomes and foursomes felt weird to her. she wouldn’t be comfortable doing anything with another man while I’m there, and she would also feel weird watching me with another woman.

So I asked the obvious follow-up. “Would you be comfortable with partner swap then?”

She said yes.

I was completely stunned. My vanilla wife just told me she’s okay with partner swapping. I was silent for a few seconds trying to process it and couldn’t even think of more questions.

I really like the idea though, and I was genuinely happy she was opening up to me. We had a wild night after that.
