<human>: Can you provide a brief rundown of the text in within 3 sentences?

We have been together 3 years including dating.

I always have known my wife had a higher number of sex partners than me by far. It has never bothered me because as far as I'm concerned what happened in the past is the past.

This holiday we had one of her old college friends staying with us who kept bringing up how crazy my wife used to be with boys. I brought it up later and found out she used to be involved in threesomes, public sex and a few other things. She said she didn't want to delve deep into any of it and it was all in the past.

I don't judge her for any of it but it made me start thinking that our sex life has been pretty tame our entire relationship compared to her past. Shes has never expressed boredom with our sex life and I made it clear if she ever wanted to try or do anything she could tell me. I have quite a few fantasies that involve some of the things she's done.

I guess mostly I'm just trying to understand why our sex life is so much more tame when compared to the past. It makes me wonder if she's craving excitement and not telling me or if she is ashamed of the past.
<bot>: My wife had a much more adventures spirit about sex before we got together. What does this mean about our sex life?
