I dont get the obsession with dating much younger 20 some y.o women. Ofcourse I know they are tigher and objectively more attractive, but within the 30,and even the 40 bracket there are plenty of beautiful women.
If, (and that's a HUGE if for most men), you manage to date a much younger women you must know it's always temporarily. 1 year would be stunning for most men.
More realistic approach for most men will be to date women around their own age, and through social/day game (combined with previously described good features as looks ,style, physique) you might catch a much younger woman every now and then. You will also age, and there are plenty of extremely horney older women ,especially the current generation.
