It was always people my own age when I was young and I started stroking long before I was able to shoot cum. Older, even two or three years older, were unobtainable. Married people were ancient! Even when I reached my late teens or twenties it was still people of my own age and I actually ran from older men and women who wanted a bit from me. Now I'm much older and fantasise about slightly younger, because anyone much younger wouldn't see anything attractive to want to play with me!! It's actually safe to think of myself as a dirty old man because I see such as unwanted by the younger generation, so there's no risk of me being molested!
Older, more mature women from my neighborhood. Especially my best friend’s mom. Fifty years later and I still stroke thinking about her.
When I was a boy I'd fantisize about the following women on television/movies. Jaclyn Smith (Kelly on Charlie's Angels) Jan Smithers (Bailey on WKRP in Cincinnati) Holly Hallstom (The Price is Right) Suzanne Somers (Chissy on Three's Company) Dawn Wells (Mary Ann on Gilligan's Island) Hailey Mills (That Darn Cat!) Barbara Eden (Jeannie from I Dream About Jeannie)
I suppose I masturbated mostly to women in their 20s as that was the main offering of Playboy, television and the Sears catalog. Some things never change!
I had serious and continuous masturbation fantasies over Jan Smithers, Dawn Wells, Holly Hallstrom and Barbara Eden
