I'm not sure the connection you are trying to make. You didn't address any of the points in my comment, instead stating a fact with an incorrect conclusion. Are the top men having more relations, yes. Do they have the opportunity to be more protected against pregnancy than previous generations, yes. Does them having more relations equal more chances to be sloppy and not fully utilize those protections in the heat of the moment. Also yes. It may not be possible to know the degree, but the general effects are easily modeled.
