ok I'll bite. what is the triangle method?
Sorry previous reply was jokey, I was in a meeting.
So triangle method is used often in intelligence work, human intelligence field, am sure other psychological fields may use this too. If you are talking to a person, and you intend to convey sexual interest or deep emotional connection or agreement, while they are talking to you, preferably about themselves, you stare first at the center of their nose-bridge. Then go to left eye, pause a moment, right eye, pause a moment, then mouth, pause a moment, and then back to rest position at nose-bridge. Has to be clockwise, no counter-clockwise. That is for something else. Doesn't work every time, but is reliable. Try it with like a girl pal who you might like to tell that you want to lick her pussy without saying the words.
