Lack of rage, especially road rage. Sure, they get upset and angry, but very, very rarely end up in testosterone fueled p*ssing contests with other drivers, for obvious reasons.
My wife can multitask i.e. she can talk on the phone, read closed caption and hear conversations in the room all at the same time. Amazing!
Having had any hint of "female traits" beaten out of me when young and tried so hard to never reveal any in public over the subsequent 50 years, it would be impossible for me to pass, as the subject line asks.
I frankly don't care what the public thinks. It's what's in my head, not theirs that counts. If wearing the correct underwear under my "prison clothes" in public helps me feel human and at peace, that's all that matters.
