Women dont have any little interest in sex than male. Only they are not vocal. Of couse sometimes its just big fight among them in mind not to express, they force themselves to refrain. To me thats a torture, still for the reputation they do that. A guy fuck around gets aplaude as Stud, a lady gets a name Slut. Thats completely unfair.
About that age 25-30, make that 25-35, thats the age women are wild. Not only intellectually matured, they know what they do, what they want, what can give, try new things, they are simply at their best.
Getting attracted is nothing wrong as they know how to represent them, alluring, desireable. Your thoughts are not corrupt, once you are 60, still will know thats the best age.
