Brutal thinly veiled but epically FAILED attempt at appearing straight and macho by way of feigning confusion about the whole matter.
you need to get smacked by a gorilla or three you wanker 
I am secure in my sexuality, unlike you. Guys who are obsessed with not appearing gay are the ones who have something to hide.

And the reason why I started this thread is because I am living in a country(Brazil) where it so common for "straight" men to have sex with smaller men taking the active role and claim to be straight. They are "straight" as long as they don't take it up the ass or suck dick. I wonder why that is

In the U.S, any man who does anything to another man is gay.
