In most of the world (Latin America, Mediterranean, Asia, Arab world, etc.) and even in the US among many blacks, it's not considered gay if you're on top. Meaning if you get a blowjob from another guy, or fukk another guy, he's the phag, not you. This used to be common knowledge even in the US and Western Europe among the working class, except that these nations are now rich and there's no more working class. And middle class people don't think this way.

But it's true, and it's obvious. That's why there are still insults like "sukk my dick" and stuff like that, that's where they come from.

Fukking or getting a blowjob from another guy means you dominate him and he's a bish.
