Sex on the brain brought to you by sex!

In the realms of science fiction

the fantastic voyage has begun.

A space craft miniaturised

inhabited by human scientists

inserted into a blood vessel

travels to the male human brain

to the sex factory.

With caution they open

the door only to hear

the meandering thoughts of:

sex, sex, sex, sex, sex

sex, sex, sex, sex, sex.

In shock from their discovery

they close the door

only to open

to confirm their discovery.

Sex, sex, sex,

tits, bum, arse,

tits bum, arse,

sex, sex, sex

tits and bums

give me more.

So there you have it

on the National Geographic 

channel of Discovery

sex is on the male brain.
