Bear,
I used to work out a little for social basketball (tried to get enough vertical jump to dunk - never quite managed that btw). My benchpress at it's best was only ever 70kg (150lbs), so I was always rather puny.
I would advise that you don't obsess about the numbers that you're putting up - ask yourself more about whether you're doing the best that you can each time you're at the gym, and if you are, then that's reason enough to feel good about yourself.
As far as I can recall, the effect of T on muscle is physiological. Off the top of my head I don't remember reading about differences in the fast twitch/slow twitch muscle ratios of males and females so the chances are being on T should allow you to pretty much be able to get as strong as a cis-male.
