You have come to the right place for support and help with your issues.
A lot of us are older but have gone through that stage at your age when things weren’t as open as now. There are common threads though in that you are finding yourself and that urge does not go away so is an indication of how you are seeing your future. What I can offer is that be patient as telling parents is not an option for you at the moment but you could have some good friends or extended family who you know well and may consider telling and see where it goes. There are also many groups now that you can find online that offer help and support which you could reach out to.
What I found is that establishing this urge would not go away I then sorted out how I would deal with it and over a period of time I started the process of coming out. It is never easy but the other key thing is to keep focus on important things in life such as your career and commitments.
