He's got 40 years of "Male/Guy" Memories, and like... 6-8 years of "Female/Girl" Memories (maybe more, but IDR the MC age).
You grab a guy more than once, and even a Japanese dude will tell you to stop. Western and Eastern Eurasians alike will definitely demand that you stop, as will most Africans.
Americans will yell at you, push you away, and possibly punch you; both North and South Americans!
Women don't, usually; because they may be slapped, thrown around, raped, or even killed. That's just a fact of life if you have tits.
Not saying it doesn't happen, but there is almost always a hesitation; hell, just because of 18,000 years of sexual dimorphism, if nothing else!
(Obviously, I'm leaving out some things in society like training, firearms, chanclas, and other advanced forms of applied violence)

Anyway.
I do NOT get why he's responding (socially/cuturally) as a woman, when he's a guy who knows he has enough (magic) power to prevent it.

These siblings can kick fucking rocks; just the most irritating people you ever have to deal with, and it grates on me! It's just... painfully irritating.
Good writing, I guess.
