Showing strength to win a female’s heart is a practice across many species and for ages.
Why is it so important to show you are strong?
To fight with her,
Over power her,
To control her,
To look down upon her or
To show other males that I can win and own her as a reward or prize
To prove to her that I’m going to protect you against all harm.
I’am strong enough to take your tantrums, your mood swings, your demotivations and be beside you in all ups and downs with a strong and stable mind and heart.
