There's an infographic chart about sexual preference as age progresses.
It seems that men start their sexual careers off wanting very vanilla, loving sex, moreso than women. Women, who start higher, peak in terms of roughness at 20 or so, then begin a slow build for preference to vanilla sex as they get older. Overall, however, women's tastes seem to stay relatively static.
Men, by contrast, have a huge swing in their patterns, shifting from vanilla sex to overwhelmingly preferring rough sex, with the preference continuing to increase as they hit old age.
While this isn't 'experimentation', the data seems to suggest that age plays a substantial role in changing preferences.
