i went through sort of the same things as you but as the other girls said you have to do it more often,and for longer periods of time,just try to really enjoy the art of dressing up and think less about arousal,i dont know how long youve been dressing but it just gets more fun and interesting the farther you go with it trust me.ive been a girl trapped in a mans body my whole life.....i say just go with it .
