When I came out, nobody had a clue that I was gay, they were all completely shocked. My mother thought I was going to tell her I was dying, my friends all thought I was joking.
Since then, I haven't changed a bit. Wait a minute...I'm gay though; I'm going to have to start my own handbag design company, start sporting a lisp and relax my wrists a little!
Just like my brother, who is straight and studying interior design, should quit his course, grow a moustache and become a police officer!
(This is my way of saying not all gay men are feminine, not all straight men are masculine, if you didn't get that).
I'd say
a lot of the people who are obsessed with masculinity, and are 'disgusted' by femininity, are
often trying to reaffirm the idea of their own masculinity because, as someone mentioned above, society has made the gay man the least desirable sexual being. Nobody wants to feel that they are undesirable, so they convince themselves that they are 'masculine', or 'straight acting', and want to surround themselves with 'masculine' people to 'confirm that'. They are attracted to masculine men because that's how they feel they should act, they're attracted to the characteristics they've been conditioned to believe they should possess. (Yes, this is very general, but I'm not saying everyone that's attracted to masculinity has an inferiority complex or other psychological issues)
Straight guys are pressured to act masculine too, you know. They're not all emotionally disconnected, rough, tough etc.
They just feel they have to act that way, because that's what men do. Catch a straight man alone with his wife / girlfriend and you'll see how emotional he is. Then all of the 'masc chasing' guys will be turned off because their unrealistic fantasy of what 'a man should be' is ruined.
People seem to have this obsession with masculinity because growing up, they've been conditioned by society to believe that it's the most desirable characteristic. Gay or feminine is inferior, straight or masculine is superior. It takes a long time, and a conscious effort to weed out conditioned thought patterns. And it really is sad to see gay people saying things like "as soon as I heard his fem voice, I was totally turned off", "he was totally hot but really feminine" etc.
