What is a str8 look? By general consensuses, Str8 looks denotes the look of manliness. Thus, all attributes that defines a man will be considered the Str8 look. Question; Why do gay men needs to 'act' str8? Are gay men not men? Then why do they need to 'act' manly? Some gay men do have problem being manly. It's all in their behaviour and attitudes of their core believe of who they are. Gay men are caught between the Man and the Woman spectrum. Those that sashay more towards the women spectrum would certainly be more womanly in behaviour and attitude. Those who stride towards the man spectrum would certainly be more manly. If a gay man is in the extreme ends of the spectrum, for the manly gay, there is no need to act because they look very str8, some even more str8 than the str8 men. The feminine gay would most likely prefers to be a woman and they are more likely to be comfortable in their own skin as a 'women'. It is usually those gay who are not sure of who they are or those who are closeted, etc. that would resort to 'acting' str8 for fear that their gayness can be spotted by their friends, family, colleagues, etc. In descriptive text in an ad; the word 'str8 acting' means the person is looking for a manly guy. That's all.
