First,
I thought:
The advent of the iron age
Made the elongation of the male sex
Unavoidable

And its main aim
The penetration
The knife, the sword, the spear

Second,
I thought:
Gunpowder, firearms
The main aim shifted
To ejaculation
And - bombs:
The mystification of the orgasm

Third,
I think:
Simulation
Through screen or helmet
Makes this
Pornography
