Hi Kova,
In my opinion, as long as you are conducting yourself in an intellectually and emotionally honest fashion, I think I would go on doing just what you have been doing. You are under no obligation to disclose your gender status any more than a cis-person is.
If you start to know someone and develop a personal relationship with them, then you might want to disclose you are trans, just so you can develop a relationship on a bedrock of honesty. That should be a rule for all relationships, of course, but trans persons are more likely to be accused of conducting their affairs in an a less-than virtuous manner if there is any room to cast blame. We are "different" and "not like the others", lol, so be prepared for people to externalize any uncomfortable feelings they may have by assuming you are responsible for their discomfort.
Just my opinion.
