Because one of the meaningful, intimate, things someone can give you was given up 23 times in a row. You're not special and that has an effect on one's psyche. You can certainly enjoy a person's company but you will never be able to connect to them on anything more than a surface level. If a person puts themselves in a very vulnerable position with numerous people it speaks volumes about their ability to maintain relationships and assess risk. Even without getting into the spirtuality of it the person is likely damaged goods. This goes equally for both genders - by the way.

Divorce rates correlate strongly with previous partner count. It's easy to find a meaningful relationship. It's hard to find a relationship where you're not going to be compared to 23 other men (or women). At 30+ you're also dealing with potential kids from the other person which in the case of fathers is a minefield should you stick around long enough to become "defacto" dad in the eye of the court.

I didn't say I had trouble finding a meaningful relationship. I said I'm having trouble finding meaning in dating 38 year old women.
