Girls And Puberty-Why Do Females Often Complain That They Wish They Were Boys?

Because you guys don't have to worry about periods or whether the boy likes you or not or the way you look and important stuff like that. You guys have so many advantages. This question was answered by a girl. No fear.

Yeah dude it's totally normal that you're interested. You're just one of the few braver ones who spoke up. Most guys are too scared at what they think others will think of them so they don't ever find out until they're married or something :)
 But yeah, periods are very upsetting if I do say so myself seeing how I am one of those who do have to deal with them every month. No it ain't always a walk in the park, but you do get used to it. And yeah some girls have it so bad they have to take birth control to help regulate it and keep it less severe. Man cramps feel like you're having a baby or something like that! In a way you sort of are. Anyway now that I have rambled enough. Hope that sort of answers your question :) 

Looks to me like you answered your own question.  You ask why girls complain and want to be more like boys, in certain respects... Then in your explanation, you give the answer to that very question.  It is because boys do not have to use all the feminine hygiene products and all the other various hassles that goes along with being a woman.
 

Male can't raped.they don't have any fear.they are stronger then women,after marriage they don't have to leave their houses but girls do.girls have to bring dowry.they have to bear childbirth pain.and brought up kids...have to listen every1....all hard things are for women.thats y they don't wana women

Blood flowing out of your vagina evry month. Isn't that enough. The pain of childbirth, raising those children, boobs, and sassy "friends." Period cramps, having to shave just about all the hair off your body, keeping the hair on your head long and  Beautiful, having designer outfits, weight, makeup, friends, mood swings, cravings, dieting, looking cute for boys. This is just a small list of our problems.

being a boy would be better. They don't have as many issues like we do

This is no knock against males, but never having to deal with menstruation, men have absolutely no idea what it's like each month.  Many women suffer severe hormonal changes which affect their emotional behavior and cause mild to severe physical discomfort.  Imagine having to go through it for forty years.  Women learn to live with it, but it can be quite unpleasant for some. 

I don't see anything unusual about your curiosity.  I'm sure all guys are curious about what girls go through.  I don't see that what you are has anything to do with puberty.  As a male, even a gay male, you experience the same changes as any other young man.
