Of course it has . One influences the other . The roles are constructed through out our history to fit the different physical characteristics of both sexes . A hormones , different builds , mental processes , etc . But for some it isnt that way . And try as they might they cant feel that way . Some women if you would see the . looks so much as big bulky dudes sorry for no links , on phone . Google the transgender bathroom photos in us controversy . You would never suspect them being a female as in having a vagina . Dlealy there was some hormonal misshap in the persons life or underwent the hormonal therapy , etc . Ohers looks like tranvestites clearly the opposite genders . But there still is a clear psychological need for them to identify as the opposite gender . Even if there isnt any physical need and they dont want to undergo any surgocal or hormonal intervention , for fear , or distrust of the procedure , or some other reason . There still is mental need for them and those are just as important . My opinion which is basically a self evident for me at this point . Is that people should not be forced or prevented from being who they are is wrong .
