Not sure what to think
My wife asked me what sex was like with old girlfriends, not going into to much detail I said ok, she said can’t be just ok must be more, I said of course but I’m not wanting to say.
When we next had sex she was sitting on me riding my cock and she said, did any of your old girlfriends fuck you like this, then started really going for it, thrusting so fast, let’s change positions she said, she went into doggie then said, show me how you fucked your old girlfriends I want to know.
I must admit it was amazing, I could picture in my head a couple of old girlfriends pussies so pretend to fuck them while fucking my wife.
My wife said after, your old girlfriends must really miss you!
This has never happened again, why would my wife randomly ask me about old girlfriends while having sex?
She needs reassurance that she is as good as your old girlfriends were in bed. She doesn't want any of them to be better than she is, so reassure her that she's the best you've ever had and keep enjoying a healthy sex life!
Sounds like it is one of her kinks. Go ahead and be honest. Start calling her by the name of an old girlfriend when you are fucking. She will like that.
She wants you to ask about old boyfriends she has fucked.
