Yes, the formative years are the crucial ones. I even speculate whether my attraction goes back to a long-haired aunt who used to innocently let me play with her locks while she dandled me on her knee....But only a psychotherapist would know for sure. I also like "hippie girls". I remember a 1967 issue of "Newsweek" about the then-developing Haight Ashbury scene which featured many photos of just such women. Also, the movie, "Woodstock" (which has remained my all-time favorite) was crucial in forming my preferences in the opposite sex (at least physically). Hey, remember how good Grace Slick looked from 1967-1970?!
