Nelli,
Hi and welcome. Finding someone who's young and CD's can be tricky but not because they don't exist.
There will be online apps that may return results but you need to be aware that the site might turn out to be akin to Grinder, the Gay meet up site that tends to err towards more casual hookups. I've no idea how many CD's would use any of the more mainstream websites but hey who knows.
LGBT venues are often the haunt of CD'ers but you'll need to be aware that if you go to one alone then Gay females may hit on you which is understandable so you'll need to be prepared to deal with that.
You could see if there are any CD/Trans support groups that meet near you. Contacting the group organiser and explaining yourself to them is the best thing to do. They will advise on if it's suitable for you to attend. As it's not uncommon for CD to be accompanied by their SO it's unlikely you'd be the only female there. You'd get much sound advice born of real life experiences from the GG's who will have, "Been there, seen it, got the tee shirt" in respect of how they coped with being out in public with their other half.
Good hunting.
