Is this why doggy style is so popular?

[SmallHorn]

I was with my fave recently and we were giving it loads in front of the mirror, as you do
She was all beauty, poise and perfection as usual when I caught a glimpse of myself in the mirror..
I'm in good shape and lean but...all I could think is..... WTF!!!!
I never thought I could look that fucking ugly!! When I cum, I cum hard and now Ugly!!! .. Woe is me.. My poor vanity is shattered..
Should have been a vampire.. no reflection..
Thoughts?

I believe there is a theory that this position is popular because of the element of dominance.
Like in the animal kingdom, male usually enters from behind.
Male instinctively wants to dominate the woman for recreation.
