I think there are... It's the MILFs who take care of their bodies more than the younger women do. They have the time and money to keep themselves in shape. At my gym all the hot women must be 35+.
My first experience there was with a young one ( No, not Nes young ) @) She was 20....thought I was never going to get rid of her.
I also think she was trying to get Pregnant, to Hook my ass.
