Bear in mind that many of us have lingering uncertainties about some element of medical/surgical transition. Most of us seem to start the transition path with testosterone. Because it's the first step and because so many of its changes are irreversible, many of us go through agonies of doubt and delay before we actually start--and then some doubt often remains.
Some are reluctant because they do not want to lose their hair or become hairy on their bodies or experience some other T-related change. Some still have doubt because they are worried about how loved ones will respond. Some have other medical issues that complicate their choices. Other people have other reasons for lingering uncertainty.
In my case, the doubt sprang purely from my fear of losing my relationship. In fact, that one element was the single most important factor in my decision NOT to transition, year after year. To help people sort out what is what, we sometimes say, "Okay, you can see the future, and you know that nobody will be put off by your transition or stop loving you. Would you still hesitate to start T?" If the answer is yes, you would still be unsure, then keep thinking about it. If the answer is no, you would definitely want to proceed, then chances are very, very good that T is right for you and that you are being held back by fear of other people's reactions.
My answer to this question would have been, "No, I wouldn't hesitate. Bring it on!" I had wanted T ever since I'd found out it was a possibility--twenty years earlier. I just didn't want to lose my partner. (ETA: I didn't want to get a hairy body at that point, nor did I want to lose head hair, but these aspects had no real bearing on my decision.)
The thing is, those reactions from family, partner(s), and friends can still be too overwhelming for some guys. I was friends with a guy who decided not to transition until his mother died. He had come out as a lesbian years and years earlier and had gone through a lot of upheaval with his parents, and the result after (apparently) years of struggle was a strong and supportive mother and father. He wasn't willing to risk their love and support over something even more...oh, radical, I suppose...than lesbianism.
So sometimes the question helps, and sometimes it doesn't. Maybe it will give you some perspective.
