1995 is the old days? The ***ual revolution was in the 60's and 70's.
As you can see in the graph, women of 20 years ago had up to 20 partners... so there's little difference to today. (This graph is for the US).
Kinda agree with the graph... but you have to wonder... the more lifetime partners the woman has... perhaps the less interest she has in settling down and the more interest she has in simply staying single and swinging?
There may be correlation and some causation, but the reasons and the mechanism behind it are not explainable by a simple graph.
