Is "Marko" an alter-ego of LE? Why does he use that? Is that for his role-playing fecal fetish games?
I can see it now; he meets the LadyBoi of his dreams, a price is negotiated and accepted.
"You are to call me Marko, and only Marko", he says.
"I will call you Polo. You will only respond to Polo", he demands.
"You will call out Marko, and I will then respond with Polo, and insert my pole into you. We will repeat this as many times as it takes to satisfy me. Then we will switch positions. Understand? You are not to stare at my neck-beard. You may stroke it if you wish."
