Hello and welcome to the Forum. You could share the pics of the tail section of your tortoise and see if it's that obvious to tell. Usually at 2 yrs old it'd be hard but we could try.
I have had a few males that I could tell at that age. I'd say it's more of a size thing than an age thing. So if they have been fed a lot and have grown pretty fast, you may be able to tell. The males are much easier to ID just from tail size usually.
