dont see why not mate,
Often, if I happen to open a set of girls that have a gay guy amongst them, I treat him the same way I treat all the other girls, I get just as much attention from the guy as I do the girls, I don’t mind a bit of flirting from the guys, its harmless as long as I clarify that im not gay.

Plus, its not just about pick up, its about bettering yourself, escalating your social skills, once you become confident enough people will recognize this, this is what is attractive, you can make friends or girlfriends/boyfriends so simply.

So to answer your question, yes I think it would work but no, I don’t know any gay pua’s.
