Sexual peak at 30 is a load of shit. Just like men they obviously get more experienced at time goes, but the whole peak thing is about women who see they are about to hit the wall and they realize they don't get as much attention as they used to. It's a desperate attempt to get the males of their age to give them attention instead of looking the way of the younger, hotter, women. File that with "real men should look for older women because they are more accomplished".
