If you are interested in the terminology used in sex research for further investigation, there is mesophilia (attraction to middle-aged adults, typically 40s and 50s) but also gerontophilia (attraction to elderly adults, typically 60s and older). Some fear the inflation of sexual orientations and want to differentiate between acquired tastes (sexual motivations) and rigidly determined preferences (sexual orientations), but not all sexual orientations are rigidly determined, so take it easy and enjoy the many men that are attracted to you!
