There are plenty of young Dom/mes. I've seen inexperienced older folks and some young folks that just seem to be naturals, so I'd suggest taking everyone with a grain of salt. Just because they say that they have the One Twoo Way, be they 19 or 91, doesn't mean that they do, or that that Way will work for you.

Some younger Dom/mes are probably on this site. You might also try Fet Life. Look in the groups in your area and there will be an "under 35" group, or a Next Gen, or some other age-related designation. Those groups started for just the reasons you say - to some it might be, "um, flattering" to be approached by an older person, and to some it's not.
