John,
Thank you for helping share your enthusiasm with the next generation of gamers! I am curious to find out what their thoughts on the issue are.
If it makes you feel better, I understand where you are coming from, in terms of a simulationist perspective. That said, I think that we have to acknowledge that this is a game, with game concepts like "hit points" and "levels." As such, I would put forth the assertion that we should avoid having gendered limits, or bonuses, in the game. We aren't simulating who is the most powerful weightlifter in the real world; instead, we are enabling people to enjoy themselves. And for that reason, I would think that we should strive to let all people enjoy their heroic images equally.
