> If I meet a partner at 40, when we start really getting old and annoyed, what am I going to hold on to?
> How lucky I am to be her 23rd partner?
You're raising a few different things here and it's hard to see what you're really concerned about, because I don't think it's the matter of divorce rates vs number of sexual partners.
If you're worried you can't find a long-term partner in your late-30s, then don't be - it's possible and tbh from personal experience dating in my 30s has been much more relaxed and chilled out than in my 20s. When you find someone will you have memories of being together stretching way back 'til your teens? Nope, but that's not necessary for happiness at all, it's one aspect of some people's relationships and not all relationships need to look alike. You'll have a different story that's unique and interesting in its own way.
If you're upset about the idea of being with someone who has been with 20+ men or women before you, then you need to work on your insecurities. How promiscuous either of you were at any time before you met will have no bearing on that whatsoever, if you are committed to each other.
It sounds a bit like you regret or resent not already being married or in a long-term relationship already if I'm honest, and are reflecting and looking around for some answers or some justifications. If that's the case then I'd suggest trying not to do that, you'll not help your own situation and you could end up going down a dark path, making yourself feel worse or being less likely to find someone.
