Let's not be obtuse, men's deodorants do smell different from women's because men smell different from women. Men's deodorants also smell stronger than women's.
People on cross sex hormones uniformly smell like a burst sewer pipe. The fact that this troon even thinks of using deodorant at all is admirable.
It is also, sadly a self own because women have more sensitive smell receptors compared to men, and that is why she is raising such a stink (lol) over it.
Rape is a strictly human construct, and a lot of animal mating behaviour can be seen as rape in a human lens (eg chickens). I believe there are theories that neolithic humans abandoned rape offspring.
Another thing that is a strictly human construct is abandonment of young. The majority of mammalia straight up eat their rejected offspring.
I wouldn't claim to know about the stats for these things, but general consesus seems to be that the chemicals responsible for "bonding" fire off close to due dates, and there is a
high margin of error, enough that we can categorise all the different ways it can go wrong.
