Here’s how to make the first move if you’re a trans guy.Firstly, don’t make the whole transgender thing a big issue.

Keep in mind that not many know much about the topic of “transgender,” so offer them the opportunity to ask questions.
It seems your boyfriend is fairly open about it, so maybe he too can answer questions your parents might have. Ask him what he's comfortable with in regards to how much your parents will know.
If your boyfriend insists you tell your parents, then you should. He's a man but at the very early stages of transitioning.
Going by the details you gave, it might not be apparent to many that he is indeed a man.
