Guys, I'm straight, indeed, straight Male. I just would like to know if the voice lessons can help my vocal range to increase.
I don't have money to afford to buy a program so I just want to know your tips and how long it took you to arrive at the point where you already have a decent female voice.
I want to be a countertenor....
I can reach high notes however, there is this flamboyant male sound that just utterly destroys it.

Singing is a hard one 

Everybody argues about it and what developed male vocal cords can and can't do and with or without falsetto.

I don't see why any normal male couldn't be a countertenor with practice though. I mean you will probably not be, like, a soprano but yeah. There seems to be good evidence that you can at least extend your vocal range very high with practice. Probably not as soft or clear as a woman, but it is still doable.

I found that this is actually not a very good place to get info about singing though, and the info is hard to find in general. But here's an interesting and informative starting point:

Also look into Adam Lopez, he seems to have a lot to say about it.

Anyone here who underwent a transition help me?

My two cents:

Your regular (non-falsetto) singing range is pretty much limited by your physical properties.
Practicing the upper range will give you more control and allow you to sing softer.

Although they say that everybody has a falsetto voice many have never found it.
