This is pure stereotype. The reality is, there is a variety of men out there, and they do end up finding partners who love them and marry them, and go on to raise families. The idea that women in general prefer the stereotypical male is totally false. Different things float different people's boats! There are nerdy girls just as there are nerdy guys. There are intellectual girls just as there are intellectual guys. There are artsy girls just as there are artsy guys. There are goth girls just as there are goth guys. And they all find each other!
Honestly, I think that men who experience gender issues need to necessarily find a way to survive in a homophobic and transphobic world and so they wrap a big protective blanket around their inner cores in order to survive. I don't blame them given the world we live in, but this leads to a development of all manner or rationalization and scornful beliefs in gendered stereotypes, when in fact, they just need to relax and accept who they are and also realize that we do live in a varied world.
Again, I'm going by the thousands of threads I've read here, the pictures in the Gallery, the accounts of how wonderful it is to feel and look and act pretty and feminine. Just read the forum! If you are in fact an exception, that's fine. If you like to go out looking like a guy wearing a skirt or it's just a fun costume for you, that's great! But you can't say that the majority of the CDers who participate here do not have the goal of crossing the gender lines.
