Geovane –
Thanks for the great discussion.
Growing up, I was a Good Guy. My wife was a Bad Girl (her own words). She had many sexual partners, while she has been my only partner. Here are a few things to consider that I have found illuminating and VERY helpful:

1. “Blooming” Early vs Late
My wife started having sex with guys at age 15. When I was 15, I could not even imagine doing such a thing. I was still into comic books, hanging with my buddies, etc. My point: People mature at different times. I was a very “late bloomer” when it came to desiring sex. Oh, mind you, I do like it now! And her, not so much. Been there, done that – many times. This very sharp contrast in our “timing” has caused us anxiety. But knowing that this stress comes from our contrasting pasts helps us isolate and deal with it. Of course, this leads to:
2. Contrasting “Numbers”
Since she started very early, her number grew – and grew. I started very late (late 20’s) and, like I said, she has been my only partner. To better make my point, if I had, say, 27 partners and she had 30, I’m sure the anxiety wouldn’t be there – we’d have our own “war stories” (and wounds) to share. Not us. Our backgrounds are lop-sided. No one’s fault – and I realize that my past helps create this as much as hers.
3. Now vs Then: People can change
When we were first together, my wife said, “If you knew me a few years ago, you wouldn’t have liked me – and I wouldn’t have liked you!” What she meant was this: she was a Bad Girl who liked only Bad Guys. To her, Good Guys were boring losers. Of course, the Bad Guys would mistreat her, and she would also be the aggressor at times. And like so many younger women, she needed to feel accepted and validated by men. But the emotional “high” she would gain by waking up naked next to a guy she just met hours before (her “win/trophy”) was only followed by an even larger “low.” Eventually, after a few years of therapy, she broke this cycle – and met me. Sadly, she no longer desires sex as it reminds her of a darker time before me. This creates anxiety as I feel she “gave herself away” before me. We’re currently working through this.

I do believe that a “Lower Number” person brings a certain degree of naivety, ignorance and expectation to the relationship. And, while a “Higher Number” person brings experience, they also bring baggage in the form of wounds, shame, guilt and pain. I am very sensitive to not “slut shaming” my wife for her past as she has told me that she’d like to forget most of it. I also realize that while she started having sex at a very early age, she needed to feel accepted and validated – I did not. She didn’t have sex out of desire (although enjoying it may have been a side bonus for her). I’m sure that if she could attain acceptance from men without sex, she would have chosen that instead.

Overall, we cannot be too general and categorize people. We’re all different, mature at various times (or never at all), in different ways – and have the option of actually changing for the worse or better. If you find someone special (as I have), don’t treat them as a sexual trophy. Treat them as a whole person. And put their life and well being before yours. Grow old with them. And after the “parts” no longer work that well, discover the joy of holding their hand.
Peace.
