I have to admit, out of all the possible sports you could be engaged in that is probably about the single most awkward.
Before I suggest anything I will state the disclaimer that I am inexperienced myself, so take what I say lightly... I had a lot of plans on a timeline that have largely been abandoned, as I began to realize that even if my plans were practical, I was hiding behind practicality and logic as a delay tactic (still am on a few things), and it sounds like that you feel you are doing the same. If the only issue is that you feel awkward wrestling with men while your parents are aware you are trans... well, there's going to be awkwardness in all of this, that's pretty much a given, and that seems like the kind of issue that may seem important now, but you won't think twice about long run. If there are other worries, such as their reaction being potentially negative, then of course that is an entirely different issue.
