If we're talking about transsexuals then they want to have a certain set of genitalia so it's too far off the mark.
Then how do you explain transmen who do not wish to have genital surgery? They take hormones, have a double mastectomy, and live entirely as men, but never change what is between their legs.
I was generalizing. I thought that was apparent. In the vast majority of cases the male child will have a penis. In some cases he will not.
Even when it comes to transmen who do not want genital surgery they still want a body that is reshapen to be masculinized assuming that in the context "transmen" means "transsexual man".
You're not trans*, so I frankly have no idea why you're continuing to act like you can speak for all of them.
